ADGI is related to BFJM in a certain way based on the English alphabetical order. In the same way, EHLN is related to FJOR. To which of the given options is GKPQ related, following the same logic?

ADGI → BFJM

EHLN → FJOR

GKPQ → ?

​Logic: The pattern is: +1, +2, +3, +4 to each letter respectively.

ADGI → BFJM
A + 1 = B
D + 2 = F
G + 3 = J
I + 4 = M 

EHLN → FJOR
E + 1 = F
H + 2 = J
L + 3 = O
N + 4 = R 

GKPQ → ?
G + 1 = H
K + 2 = M
P + 3 = S
Q + 4 = U 

So, GKPQ becomes HMSU.

Thus, the correct option is (b) HMSU
