- The 8085/8080A has six general-purpose registers to store 8-bit data
- These are identified as B, C, D, E, H, and L
- They can be combined as register pairs - BC, DE, and HL - to perform some 16-bit operations

Consider the following registers:a. A and B registersb. B and C regist...
In the 8085 microprocessor, there are several 8-bit registers that can be paired together to form a 16-bit register. Let's analyze each option to determine which registers can be paired together.
a. A and B registers:
The A register is the Accumulator and is used for various arithmetic and logical operations. The B register is a general-purpose register. These two registers cannot be paired together to form a 16-bit register.
b. B and C registers:
Both the B and C registers are general-purpose registers. These two registers can be paired together to form a 16-bit register. This 16-bit register is often used as a memory pointer.
c. D and E registers:
Similar to the B and C registers, the D and E registers are also general-purpose registers. These two registers can be paired together to form a 16-bit register. This 16-bit register is often used as a memory pointer.
d. H and L registers:
The H and L registers are special-purpose registers commonly known as the High and Low registers. These registers are used to store the higher and lower bytes of a 16-bit address. The H and L registers can be paired together to form a 16-bit register.
Based on the above analysis, the correct answer is option C, which states that the B and C registers, as well as the D and E registers, can be paired together to form a 16-bit register in the 8085 microprocessor.

Based on the above analysis, the correct answer is option C, which states that the B and C registers, as well as the D and E registers, can be paired together to form a 16-bit register in the 8085 microprocessor.
