Select the pair that follows the same pattern as that followed by the two pairs givenbelow. Both pairs follow the same pattern.

INN : JPM

GBG : HDF​​

Given: 

INN : JPM

GBG : HDF​​

Logic: 1st letter + 1 = 4th letter, 2nd letter + 2 = 5th letter and 3rd letter - 1 = 6th letter

For, INN : JPM

I + 1 = J, N + 2 = P, N - 1 = M

For, GBG : HDF

G + 1 = H, B + 2 = D, G - 1 = F

Now, we check each options.

Option (a): OEY : PGZ (Not Follow)

O + 1 = P, E + 2 = G, Y - 1 $$\neq$$​ Z

Option (b): NMN : OOM (Follow)​

N + 1 = O, M + 2 = O, N - 1 = M

Option (c): MGS : NIQ (Not Follow)​

M + 1 = N, G + 2 = I, S - 1 $$\neq$$​ Q

Option (d): TKR : ULS (Not Follow)​

T + 1 = U, K + 2 $$\neq$$​ L, R - 1 $$\neq$$​ S

Thus, correct option is (b).
