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.

BAL : ODE :: AGR : ?

UJD

Pattern followed is :

BAL : ODE

B(2) + 3 = (5)E , A(1) + 3 = (4)D , L(12) + 3 = (15)O

EDO , write it in reverse order = ODE

Similarly ,

AGR : ?

A(1) + 3 = (4)D ,G(7) + 3 = (10)J , R(18) + 3 = (21)U

DJU , write it in reverse order = UJD

UJD , is correct answer .
