If the HLT instruction of a 8085 microprocessor is executed then,a)the...
HLT → is a 1-byte instruction.
→ processor stops executing and enters wait state
→ no register contents are affected.
→ the address bus and data bus are placed in high impedance state

Explanation:
When the HLT (Halt) instruction of a 8085 microprocessor is executed, the following happens:
• The microprocessor enters into a halt state and the buses are tri-stated.
• The microprocessor does not execute any further instructions until a reset is issued.
• The microprocessor does not generate any more control signals, including the read and write signals to the memory and I/O devices.
• The microprocessor remains in this state until it is reset.
Therefore, option 'B' is the correct answer.
