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 letter-cluster 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.

IL - FI

B.

OR - LO

C.

QT - NP

D.

MP - JM

Correct option is C

Logic: Both letters move 3 positions backward.
A. IL → FI
I → F = −3
L → I = −3 
B. OR → LO
O → L = −3
R → O = −3 
C. QT → NP
Q → N = −3
T → P = −4 
D. MP → JM
M → J = −3
P → M = −3 
Only Option C does not follow this pattern.
Correct Answer: (C) QT – NP
