Show answer & explanation

Correct answer: C

Answer: ISS

Explanation:

  • First letters form the sequence: C, E, G, I, K — each advances by two letters in the alphabet (C → E → G → I → K).

  • The second and third letters in each group are the same and form the sequence: M, O, Q, S, U — each advances by two letters (M → O → Q → S → U).

  • Combine the two patterns: the missing group needs first letter I and repeated letter S, giving ISS.

  • Check: CMM, EOO, GQQ, ISS, KUU.
