Three of the following four letter-clusters are alike in a certain way and thus form a group. Which is the one that does NOT belong to that group?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. ZAB.
Logic: 1st letter + 1 = 2nd letter; 2nd letter + 2 = 3rd letter
Except ZAB, all words follow the same logic.
While ZAB ⇒ Z + 1 = A; A + 2 = C ≠ B
