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: B
Explanation
The correct answer is option 2 i.e. ACD.
Logic: 1st letter + 2 = 2nd letter; 2nd letter + 2 = 3rd letter
Except, ACD all follow the same logic while ACD → A + 2 = C; C + 2 = E ≠ D
