Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. GZTNK.
The logic used here is: 1st letter - 7 = 2nd letter, 2nd letter - 6 = 3rd letter, 3rd letter - 5 = 4th letter, 4th letter - 4 = 5th letter
Option 1: GZTNK: G - 7 = Z, Z - 6 = T, T - 5 = O, O - 4 = K, This does not follow the logic.
