Concept:In fixed-shift letter coding, each letter is moved by the same number of positions in the alphabet.Explanation:Compare PRIMATE with MOFJXQB:P→M, R→O, I→F, M→J, A→X, T→Q, E→B.Each letter is shifted 3 places backward, i.e. −3.Here A−3 wraps to X.Now apply the same rule to COW:C−3=ZO−3=LW−3=TSo the code is ZLT.Answer:ZLT (Option A)
