HOMD

The pattern followed is :

AREA : BRFA

A(1) + 1 = (2)B , R(18) :- same R , E(5) + 1 = (6)F , A(1) :- same A

&   BABY : CACY

B(2) + 1 = (3)C , A(1) :- same A , B(2) + 1 = (3)C , Y(25) :- same Y

Similarly ,

GOLD : ?

G(7) + 1 =(8)H , O(15):-same O , L(12) + 1 = (13)M , D(4) :- same D

HOMD , is correct answer .
