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)​

​Option A: MQ - UZ

M +3 →P not Q

U +3 →X not Z

Option B: GJ - PS

G +3 →J

P +3 →S

Option C: EH - NQ

E +3 →H

N +3 →Q

Option D: JM - SV

J +3 →M

S +3 →V​​

So the odd one out is MQ-UZ.

Thus, correct option is (a).
