  1. In an 8085 microprocessor based system, the contents of SP are 1000H. PUSH B instruction will transfer the contents of registers B and C respectively for memory locations—
    1. 0FFF H and 0FFE H
    2. 0FFE H and 0FFF H
    3. 1000 H and 0FFF H
    4. 1000 H and 1001 H
Correct Option: A

As we know that when PUSH is executed, the stack pointer (SP) register is decremented by 2.

Hence alternative (A) is the correct answer.
