Select the triad that follows the same pattern as the one followed by the two triads given below. Both triads follow the same pattern.
NT-PV-RU
LR-NT-PS

Given: 

NT-PV-RU
LR-NT-PS

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

2nd letter + 2 = 4th letter and 4th letter - 1 = 6th letter

For, NT-PV-RU

N + 2 = P, P + 2= R

T + 2= V, V - 1 = U

For, LR-NT-PS

L + 2 = N, N + 2 = P

R + 2 = T, T - 1 = S

Now, we check each options.

Option (a): IP-LR-NO (Not Follow)

I + 2 $$\neq$$ L, L + 2 = N 

P + 2 = R, R - 1 $$\neq$$ O​

Option (b): IP-LS-NO (Not Follow)​

I + 2 $$\neq$$ L, L + 2 = N 

P + 2 $$\neq$$​ S, S - 1 $$\neq$$ O

Option (c): JP-LR-NO (Not Follow)​

J + 2 = L, L + 2 = N 

P + 2 = R, R - 1 $$\neq$$ O

Option (d): JP-LR-NQ (Follow)​

J + 2 = L, L + 2 = N

P + 2 = R, R - 1 = Q

Thus, correct option is (d).
