MCQ (Single Correct Answer)

-0.6

In an 8085 system, a PUSH operation requires more clock cycles than a POP operation. Which one of the following options is the correct reason for this?

For POP, the data transceivers remain in the same direction as for instruction fetch (memory to processor), whereas for PUSH their direction has to be reversed.

Memory write operations are slower than memory read operations in an 8085 based system.

The stack pointer needs to be pre-decremented before writing registers in a PUSH, whereas a POP operation uses the address already in the stack pointer.

Order of registers has to be interchanged for a PUSH operation, whereas POP uses their natural order.
