Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Role of MDR.
The Memory Data Register (MDR) temporarily holds data that is being transferred to or from memory.
Step 2: Communication link.
MDR serves as a buffer between CPU and memory/peripherals, facilitating data movement.
