Ai-b, ii-d, iii-a, iv-c ✓ Correct

Bi-a, ii-b, iii-c, iv-d

Ci-c, ii-a, iii-b, iv-d

Di-d, ii-c, iii-a, iv-b

Correct answer: (A) i-b, ii-d, iii-a, iv-c

Explanation

The ALU carries out arithmetic and logic operations such as AND, OR and NOT.

The control unit fetches each instruction in turn and manages its execution.

RAM stores the part of the operating system and programs currently in use.

ROM stores the bootstrap loader and BIOS needed to start the computer.

The ALU and control unit together form the central processing unit.

RAM is volatile while ROM keeps its contents without power.
