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.

KING : HFKD :: FRKM : ?

COHJ

Pattern folllowed is :

KING : HFKD

K(11) - 3 = (8)H , I(9) - 3 = (6)F , N(14) - 3 = (11)K , G(7) - 3 = (4)D

Similarly ,

FRKM : ?

F(6) - 3 = (3)C ,R(18) - 3 = (15)O , K(11) - 3 = (8)H , M(13) - 3 = (10)J

COHJ , is correct answer .
