Three of the following four letter-cluster pairs are alike in a certain way and thus form a group. Which is the letter-cluster pair that does NOT belong to that group?

(Note: The odd one out is not based on the number of consonants/vowels or their positions in the letter-cluster.)

Logic: Pairs A, B, and C decreasing by -3, while decreasing by -2.

Option (a): QS - NP → Q (-3) → N, S (-3) → P,

Option (b): JL - GI → J (-3) → G, L (-3) → I,

Option (c): XZ - UW → X (-3) → U, Z (-3)→ W,

Option (d): MN - KL → M (-2) → K, N (-2) → L,

Odd one out: (MN - KL) because it follows a different shift pattern.

Thus, the correct option is (d) MN - KL.​
