The correct answer is option C) Operation code.

Operation code, also known as opcode, is the instruction code used in machine or assembly language that specifies the basic operations of the CPU (Central Processing Unit). It is a fundamental part of the instruction set architecture of a computer.

Here is a detailed explanation:

1. Machine Code:
Machine code is a low-level programming language that consists of binary instructions executed directly by the CPU. Each instruction is represented by a specific pattern of 0s and 1s. Machine code is specific to the hardware architecture of the computer and is not easily human-readable.

2. Instruction Code:
Instruction code is a broader term that encompasses both machine code and assembly code. It refers to the set of instructions that a computer can execute. These instructions specify the operations that the CPU should perform, such as arithmetic calculations, data movement, and control flow.

3. Operation Code (Opcode):
The operation code is the part of the instruction that specifies the operation to be performed by the CPU. It determines the type of operation, such as addition, subtraction, multiplication, or branching. The opcode is usually represented by a binary or hexadecimal value.

4. Assembly Code:
Assembly code is a low-level programming language that uses mnemonics to represent machine instructions. It is a human-readable representation of the machine code. Each assembly instruction corresponds to a specific machine instruction and includes an opcode along with optional operands.

5. Language Code:
Language code is a term that is not directly related to the instruction code used in machine or assembly language. It could refer to a programming language such as C, Python, or Java, which are higher-level languages that provide more abstraction and easier programming compared to machine or assembly language.

In summary, the instruction code used in machine or assembly language that specifies the basic operations of the CPU is the operation code (opcode). It is a fundamental part of the instruction set architecture and determines the type of operation to be performed by the CPU.

Direction: Read the passage carefully and select the best answer to each question out of the given five alternatives.Banks will conduct special clearing operations for annual closure of government accounts on March 31, which is the last day of the current fiscal year, the RBI has said. The Reserve Bank has issued directions to the banks for smooth clearing operation and asked them to mandatorily participate in it. With regard to annual closing of accounts related transactions of the central and state governments, special measures are put in place for 2020-21, the RBI has instructed all the member banks to maintain sufficient balance in their clearing settlement account. Normal clearing timings as applicable to any working Wednesday shall be followed on March 31, 2021, the RBI said in a notification addressed to the member banks, urban and state cooperative banks, payments banks, small finance banks as well as the NPCI. To facilitate accounting of all the government transactions for the current financial year 2020-21 by March 31, 2021, it has been decided to conduct special clearing exclusively for government cheques across the three CTS grids on March 31, 2021, the RBI said.Under this, presentation clearing will take place between 1700 to 1730 hrs and return clearing will take place between 1900 and 1930 hrs at the three CTS (cheque truncation system) grids located in New Delhi, Chennai and Mumbai. “It is mandatory for all banks to participate in the special clearing operations on March 31, 2021. All the member banks under the respective CTS grids are required to keep their inward clearing processing infrastructure open during the special clearing hours and maintain sufficient balance in their clearing settlement account to meet settlement obligations arising out of the special clearing,” said the regulator. Besides, it has asked the banks under the respective CTS grids to adhere to the instructions issued to them by the President of the respective CTS grid. Under the CTS system, there is no need to present a cheque physically for clearance, instead an electronic image is being transmitted to the paying branch through the clearing house, with the relevant data. This eliminates the cost of movement of the physical cheques and reduces time for collection and clearance of cheques. All government transactions done by agency banks for 2020-21 must be accounted for within the same financial year, the RBI said. The central bank said all agency banks should keep their designated branches open for over the counter transactions related to government transactions up to the normal working hours on March 31, 2021. “Transactions through National Electronic Funds Transfer (NEFT) and Real Time Gross Settlement (RTGS) System will continue up to 2400 hours as hitherto on March 31, 2021. “Special clearing will be conducted for collection of government cheques on March 31, 2021 for which the Department of Payment and Settlement Systems (DPSS), RBI will issue necessary instructions,” it said. With regard to reporting of central and state government transactions to RBI, including uploading of GST/e-receipts luggage files, the reporting window of March 31, 2021 will be extended and kept open till 1200 hours on April 1, 2021, the RBI said.What can you say from the following sentence?"It is mandatory for all banks to participate in the special clearing operations on March 31, 2021”
