A) O, P

B) P, Q

C) R, R

D) S, R

Answer:

Option C

Explanation:

The given sequence is a combination of two series:

I. C, F, I, L, O, ? ; and  II. Z, X, V, T, ?;

The pattern in I is : $C+3 \rightarrow F, F+3 \rightarrow I, I+3 \rightarrow L,$

$L+3 \rightarrow O, O+3 \rightarrow R,$

The pattern in II is : $Z-2 \rightarrow X, X-2 \rightarrow V, V-2 \rightarrow T, T-2 \rightarrow R,$

Hence the answer is (c).
