Question

Based on the English alphabetical order, three of the following four letter-cluster pairs are alike in a certain way and thus form a group. Which pair 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).

A.

OJ-MP

B.

SN-QU

C.

QL-OR

D.

UP-SV

Correct option is B

Logic: (1st Letter - 5) = 2nd Letter And (3rd Letter + 3) = 4th Letter.
Let's check each options:
Option A: OJ-MP
O -5 → J, M +3 → P
Option B: SN-QU
S -5 → N, Q +3 → \not= U (Not Follow)
Option ​C: QL - OR
Q - 5 → L, O + 3 → R
Option D: UP - SV
​U - 5 → P, S + 3 → V
Hence, the pattern followed in Options A, C, and D, but not in Options B.
So,  SN - QU does not belong to the group.
Thus, the correct option is: (b)
