Based on the English alphabetical order, three of the following four letter-clusters 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.)

Logic: Pattern are +1, -5 in English alphabet.

Let's check all options:

Option (a): UVQ
U + 1 = V
V - 5 = Q 

Option (b): IMH  (Pattern Not Follow)
I + 4 = M
M - 5 = H
​Option (c): WXS
W + 1 = X
X - 5 = S 
​Option (d): IJE
I + 1 = J
J - 5 = E 

Odd One Out: Option (b) IMH does not follow the same pattern as other options follow to making it odd one out.

Thus, the correct option is (b) IMH.
