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: A
Explanation

Except for ILO, all words follow the same logic. While ILO → I + 3 = L; L + 4 = P ≠ O
