Show answer & explanation
Correct answer: A
Concept: Coding-decoding letter-analogy items apply ONE fixed rule to every letter of the first word to produce the second word. The rule can combine (a) replacing each letter under a substitution scheme and (b) changing the letters' order. Once the exact rule is confirmed on the given pair, the same rule applied to the third word gives the answer.
Applying the rule to HABIT : GRYZS:
Replace each letter of HABIT with its alphabet-opposite letter (the letter it pairs with when A is paired with Z, B with Y, C with X, and so on): H -> S, A -> Z, B -> Y, I -> R, T -> G, giving the string SZYRG.
Read SZYRG from its last letter to its first: G, R, Y, Z, S - exactly GRYZS - confirming the two-part rule: alphabet-opposite substitution, then reversal of the resulting string.
Applying the confirmed rule to PEDAL:
Replace each letter of PEDAL with its alphabet-opposite letter: P -> K, E -> V, D -> W, A -> Z, L -> O, giving the string KVWZO.
Read KVWZO from its last letter to its first: O, Z, W, V, K.
Cross-check (independent re-derivation in the reverse order):
Reverse PEDAL first to get LADEP.
Then take the alphabet-opposite of each letter: L -> O, A -> Z, D -> W, E -> V, P -> K, giving O, Z, W, V, K again - the identical result obtained the other way, confirming the answer independently.
Result: The fourth term is the code obtained by applying this two-step rule to PEDAL: O, Z, W, V, K.
