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.

HKRC : ENOF : : SRYK : ?

PUVN

Pattern followed is :

HKRC : ENOF

H(8) - 3 = (5)E , K(11) + 3 = (14)N , R(18) - 3 = (15)O , C(3) + 3 = (6)F

 Similarly ,

SRYK : ?

S(19) - 3 = (16)P , R(18) + 2 = (21)U , Y(25) - 3 = (22)V , K(11) + 3 = (14)N
