Correct option is B
Given:
GN-JQ-MP
DK-GN-JM

Logic: 1st letter + 3 = 3rd letter and 3rd letter + 3 = 5th letter
2nd letter + 3 = 4th letter and 4th letter - 1 = 6th letter
For, GN-JQ-MP
G + 3 = J, J + 3 = M
N + 3 = Q, Q - 1 = P
For, DK-GN-JM
D + 3 = G, G + 3 = J
K + 3 = N, N - 1 = M
Now, we check each options.
Option (a): JQ-MT-PR (Not Follow)
Option (a): JQ-MT-PR (Not Follow)
J + 3 = M, M + 3 = P
Q + 3 = T, T - 1 R
Option (b): JQ-MT-PS (Follow)
J + 3 = M, M + 3 = P
Q + 3 = T, T - 1 = S
Option (c): IQ-NT-PR (Not Follow)
Option (c): IQ-NT-PR (Not Follow)
I + 3 M, M + 3 = P
Q + 3 = T, T - 1 R
Option (d): IQ-MT-PR (Not Follow)
I + 3 M, M + 3 = P
Q + 3 = T, T - 1 R
Thus, correct option is (b).
