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 + 5 = 2nd letter and 2nd letter - 3 = 3rd letter

Now, we check each options.

Option (a): TYV (Follow)

T + 5 = Y and Y - 3 = V

Option (b): RWT (Follow)​

R + 5 = W and W - 3 = T

Option (c): XCA (Not Follow)​

X + 5 = C and C - 3 $$\neq$$​ A

Option (d): LQN (Follow)​

L + 5 = Q and Q - 3 = N

So, option a, b, d follow except c

Thus, correct option is (c).
