KMO, OQS, SUW, ....?

Answer: The correct answer is (B) WYA.

Explanation:

The pattern follows a sequence where each letter in a group is advanced by 4 positions in the alphabet to form the next group.

1. First letter: K → O (K+4 = O), O → S (O+4 = S).
   Therefore, S+4 = W.
2. Second letter: M → Q (M+4 = Q), Q → U (Q+4 = U).
   Therefore, U+4 = Y.
3. Third letter: O → S (O+4 = S), S → W (S+4 = W).
   Therefore, W+4 = A (wrapping around the alphabet).

Thus, the next term in the series is WYA.
