Show answer & explanation

Answer: (B) A

Explanation

Replace each letter by its opposite letter in the alphabet (A↔Z, B↔Y, …, a pair of positions adding to 27) and then move one step forward. LEMON: opposites are O, V, N, L, M; one step forward gives P, W, O, M, N = PWOMN, which matches. SHIRT: opposites are H, S, R, I, G; one step forward gives I, T, S, J, H = ITSJH.
