To solve this question, we need to recognize the pattern or rule that is being applied to the given letters. Let's analyze the pattern:
Q -> P -> O -> N -> M
P -> O -> N -> M -> L
O -> N -> M -> L -> K
From the pattern, we can observe that each letter is being shifted one position to the left in the alphabet. Applying the same rule to the given letters, we get:
QPO -> OPN -> NMO -> MNL -> LMK
SRQ -> RQP -> QPO -> PON -> ONM
UTS -> TSR -> RSP -> SPQ -> PQO
WVU -> UVT -> VTS -> TSR -> SRQ
The next letters in the sequence would be:
OPN -> NMO -> MNL -> LMK -> KJL
RQP -> QPO -> PON -> ONM -> NML
TSR -> RSP -> SPQ -> PQO -> OPN
UVT -> VTS -> TSR -> SRQ -> RQP
Therefore, the correct answer is B) YXW, as it follows the same pattern of shifting each letter one position to the left in the alphabet.
