**********************************************************

THE LOGIC FOLLOWED HERE IS :

PAG : NYE :: TUB : RSZ :: RICE : ?

P → (-2) → N

A → (-2) → Y

G → (-2) → E

And,

TUB : RSZ,

T → (-2) → R

U → (-2) → S

B → (-2) → Z

Similarly,

R → (-2) → P

I → (-2) → G

C → (-2) → A

E → (-2) → C

Thus, PGAC is correct.
