Correct answer: B

Concept

In a letter series, each fixed character position can form its own sequence. Converting letters to alphabet positions exposes a repeated shift vector, which can then be applied to the latest term.

Application

  1. Compare AYBZC with DWEXF. The five position-wise alphabet shifts are +3, −2, +3, −2, +3.

  2. The same shift vector appears from DWEXF to GUHVI and from GUHVI to JSKTL, so it is the governing rule.

  3. Apply the vector to JSKTL: J + 3 = M, S − 2 = Q, K + 3 = N, T − 2 = R, and L + 3 = O.

Cross-check

The odd positions A–D–G–J–M, B–E–H–K–N, and C–F–I–L–O each advance by three letters; the even positions Y–W–U–S–Q and Z–X–V–T–R each move back by two letters.

Therefore, the missing term is MQNRO.
