Based on the alphabetical order, three of the following four letter-clusters are alike in a certain way and thus form a group. Which letter-cluster does not belong to that group?
(Note: The odd one out is not based on the number of consonants/vowels or their position in the letter cluster.)
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. ROS.
Logic: 1st letter - 3 = 2nd letter; 2nd letter + 2 = 3rd letter
Except ROS, All words follow the same logic. While ROS → R - 3 = O; O + 2 = Q ≠ S
