Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. GED.
The logic used here is: 1st letter - 2 = 2nd letter, 2nd letter - 2 = 3rd letter
1: SQO: S - 2 = Q, Q - 2 = O
2: YWU: Y - 2 = W, W - 2 = U
3: MKI: M - 2 = K, K - 2 = I
4: GED: G - 2 = E, E - 2 = C:This does not follow the logic.
