D Correct answer
Explanation

Index addressing mode computes the effective address by adding a displacement (constant) to the contents of an index register. Absolute mode uses only a constant address in the instruction, indirect mode dereferences a pointer to get the address, and immediate mode embeds the operand value directly in the instruction.
