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 letter-cluster 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: 1st letter - 7 = 2nd letter, 2nd letter - 3 = 3rd letter and 3rd letter - 5 = 4th letter

Now, we check each options.

Option (a): BURM (Follow)

B - 7 = U, U - 3 = R, R - 5 = M

Option (b): QJGB (Follow)​

Q - 7 = J, J - 3 = G, G - 5 = B

Option (c): HAXS (Follow)​

H - 7 = A, A - 3 = X, X - 5 = S

Option (d): TMJF (Not Follow)​

T - 7 = M, M - 3 = J, J - 5 $$\neq$$​ F

Thus, correct option is (d).
