Based on the English alphabetical order, three of the following four letter-clusters arealike in a certain way and thus form a group. Which letter-cluster DOES NOT belong tothat group?(Note: The odd one out is not based on the number of consonants/vowels or theirposition in the letter-cluster.)​​

Logic: 1st letter + 2 = 2nd letter and 2nd letter - 3 = 3rd letter

Now, we check each options.

Option (a): UWT (Follow)

U + 2 = W and W - 3 = T

Option (b): OQN (Follow)​

O + 2 = Q and Q - 3 = N

Option (c): GHF (Not Follow)​

G + 2 $$\neq$$​ H and H - 3 $$\neq$$​ F

Option (d): MOL (Follow)​

M + 2 = O and O - 3 = L

Thus, correct option is (c).
