Correct answer: B

Explanation

  1. K to I and E to C show a shift of 2 places back. B to Z and A to Y agree once you wrap past A to the end of the alphabet.

  2. COOK: C to A, O to M, O to M, K to I.

  3. The code is AMMI.

Worth noting

Letters near the start wrap around: two places back from B is Z, and from A is Y. BNNJ uses a shift of only 1.
