1. ARead a number from input port and store it in memory
2. BRead a number from input device with address 8000 H and store it in memory at location 8001 H
3. CRead a number from memory at location 8000 H and store it in memory location 8001 H
4. DLoad A with data from input device with address 8000 H and display it on the output device with address 8001 H

Show answer & explanation

Correct answer: C. Read a number from memory at location 8000 H and store it in memory location 8001 H

Explanation

LDA 8000H loads A from memory, ADD B adds 30H, and STA 8001H stores the result. The program reads a number from 8000H and stores a result at 8001H (after adding 30H).
