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

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

Ci-d, ii-c, iii-b, iv-a ✓ Correct

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

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

Explanation

RAM holds the programs and data currently in use so the processor can access them quickly during operation.

RAM pairs with holding programmes currently being run, since it is the fast temporary working memory.

DVD-ROM pairs with can be written only once, being an optical disc used mainly for distributing fixed content.

ALU pairs with performing all computations and comparison operations, as it is the arithmetic and logic unit.

CPU pairs with brain of the computer, since it controls and carries out the processing.

Unlike RAM, a DVD retains its stored data without any power supply.
