Show answer & explanation

Correct answer: C

Cipher rule: replace every letter by its alphabet-mirror, so the position of the original letter and the position of its code letter add up to 24 (counting A=0, B=1, ... Y=24). This gives the fixed pairs A↔Y, B↔X, C↔W, D↔V, E↔U, F↔T, G↔S, H↔R, I↔Q, J↔P, K↔O and L↔N.

Apply it to each word:

(A) QUAKE → Q→I, U→E, A→Y, K→O, E→U = IEYOU = (III)

(B) OFTEN → O→K, F→T, T→F, E→U, N→L = KTFUL = (I)

(C) PEACH → P→J, E→U, A→Y, C→W, H→R = JUYWR = (IV)

(D) DRIVE → D→V, R→H, I→Q, V→D, E→U = VHQDU = (II)

So the correct matching is (A)-(III), (B)-(I), (C)-(IV), (D)-(II).
