RST: UWY: ZCF
Logic: In first letter cluster letter increases by +1, second letter cluster increases by +2, and third letter clustert increases by +3
Explanation:
ABC: DFH: ILO
A+1=B, B+1=C: D+2=F, F+2=H: I+3=L, L+3=O
RST: UWY: ZCF
R+1=S, S+1=T: U+2=W, W+2=Y: Z+3=C, C+3=F
Similarly,
A.) STU: VWX: YZA
S+1=T, T+1=U: V+2=W, W+2=X: Y+3=B, B+3=E (Does not follow)
B.) OPQ: RTV: WYA
O+1=P, P+1=Q: R+2=T, T+2=V: W+3=Z, Z+3=C (Does not follow)
C.) FGH: IKM: NQT
F+1=G, G+1=H: I+2=K, K+2=M: N+3=Q, Q+3=T (Follows)
D.) EFG: HKN: ORU
E+1=F, F+1=G: H+2=K, K+2=M: O+3=R, R+3=U (Does not follow)
Thus, Option C is the correct answer.
