GTBK is related to KRFI in a certain way based on the English alphabetical order. In the same way, NSFX is related to RQJV. To which of the given options is EKVO related, following the same logic?

GTBK → KRFI

NSFX → RQJV

EKVO → ? 

​Logic: 1st and 3rd + 4, 2nd and 4th - 2.

G + 4 = K

T - 2 = R

B + 4 = F

K - 2 = I

N + 4 = R

S - 2 = Q

F + 4 = J

X - 2 = V

Now apply the same logic to EKVO → ? 

E + 4 = I

K - 2 = I

V + 4 = Z

O - 2 = M

So, EKVO → IIZM

Thus, the correct option is (b) IIZM.
