Four pairs of letter-clusters have been given out of which three are alike in some manner and one is different. Select the one that is different.

Logic: Check letter position shifts (alphabet numbers).

A: FD - KI
F(6) → K(11) = +5
D(4) → I(9) = +5 

B: NL-SQ
N(14) → S(19) = +5
L(12) → Q(17) = +5 

C: TP-WV
T(20) → W(23) = +3
P(16) → V(22) = +6 ✘ (not same shift)

D: HF-MK
H(8) → M(13) = +5
F(6) → K(11) = +5 

Three pairs follow +5 shift rule.
Only C does not.

Final Answer:
TP – WV

Final Correct Option:
(c)
