- B. Data segment
- C. Extra segment
- D. Pointer register
Explanation
The correct answer is D) Pointer register.Pointer registers are specifically designed to store memory addresses. When calculating variable offsets, the CPU adds the offset value (distance from the beginning of the memory block) to the base address stored in the pointer register to locate the specific memory address of the variable.
