Question

Based on the alphabetical order, three of the following four are alike in a certain way and thus form a group. Which is the one that 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.)

The correct answer is

SOP

Checking the letter gaps: QMJ (Q to M is -4, M to J is -3), VRO (V to R is -4, R to O is -3), KGD (K to G is -4, G to D is -3), all sharing the same -4, -3 pattern.

SOP breaks this pattern: S to O is -4, but O to P is +1, not matching the consistent -4, -3 gap.

Hence, SOP is the one that does not belong to the group.
