Select the triad that follows the same pattern as the one followed by the two triadsgiven below. Both triads follow the same pattern.

DK-GN-JM

FM-IP-LO​​​

Given:

DK-GN-JM

FM-IP-LO​​​

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

For, DK-GN-JM

 D + 3 = G, G + 3 = J

K + 3 = N, N - 1 = M

For, FM-IP-LO

F + 3 = I, I + 3 = L

M + 3 = P, P - 1 = O

Now, we check each options.

Option (a): GO-KS-NP (Not Follow)

G + 3 $$\neq$$ K, K + 3 = N

O + 3 $$\neq$$ S, S - 1 $$\neq$$ P​

Option (b): HO-KR-NQ (Follow)​

H + 3 = K, K + 3 = N

O + 3 = R, R - 1 = Q

Option (c): HO-KR-NP (Not Follow)​

H + 3 = K, K + 3 = N

O + 3 = R, R - 1 $$\neq$$ P

Option (d): GO-KR-NP (Not Follow)​

G + 3 $$\neq$$ K, K + 3 = N

O + 3 = R, R - 1 $$\neq$$ P

Thus, correct option is (b).
