Select the option that is related to the third letter-cluster in the same way as the second letter-cluster is related to the first letter-cluster. PV : MQ :: FB : ?

CX DW DX CW

CW

Pattern followed is : PV : MQ P(16) - 3 = (13)M , V(22) - 5 = (17)Q Similarly ,  FB : ? F(6) - 3 = (3)C , B(2) - 5 = (23)W CW , is correct answer .
