Show answer & explanation
Correct answer: C
In an indirect addressing scheme, the address field of the instruction does not contain the effective address directly. Instead, it contains the memory address where the actual effective address (the address of the operand) is stored. Therefore, the CPU must perform an additional memory access to retrieve the effective address before accessing the operand.
