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

KG-NI-PS

NJ-QL-SV​​

KG - NI - PS

NJ - QL - SV

Logic: 1st letter + 3 = 3rd letter, 3rd letter + 2 = 5th letter

2nd letter + 2 = 4th letter, 4th letter + 10 = 6th letter

For, KG - NI - PS

K + 3 = N, N + 2 = P

G + 2 = I, I + 10 = S

For, NJ - QL - SV

N + 3 = Q, Q + 2 = S

J + 2 = L, L + 10 = V

Now, we check each options.

Option (a): RM - TP - VZ (Not follow)

R + 3 $$\ne$$ T, T + 2 = U

M + 2 $$\ne$$​ P , P+ 10 = Z

Option (b): QM - TO - VY (Follow)

Q + 3 = T, T + 2 = V

M + 2 = O, O + 10 = Y

Option (c): QM - TO - VZ (Not follow)

Q + 3 = T, T + 2 = V

M + 2 = O, O + 10 $$\ne$$​ Z

Option (d): RM - TO - VZ (Not follow)

R + 3 $$\ne$$​ T, T + 2 = V

M + 2 = O, O + 10 $$\ne$$ Z​

Thus, correct option is (b).
