Select the triad that follows the same pattern as that followed by the two triads given below. Both triads follow the same pattern.
NJ-QM-TV
JF-MI-PR​

NJ – QM – TV

JF – MI – PR

Let’s analyze the letter positions in each triad.

Triad 1: NJ – QM – TV

N + 3 → Q, Q + 3 → T
J + 3 → M, M + 9 → V

Triad 2: JF – MI – PR

J + 3 → M, M + 3 → P
F + 3 → I, I + 9 → R

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

Now test options:

Option (a): GB – ID – LM

G (7) → I (9) → L (12): +2, +3 (Not follow)

Option (b): FB – IE – LM

F (6) → I (9) → L (12): +3, +3

B (2) → E (5) → M (13): +3, +8  (Not follow)​

​Option (c): GB – IE – LM

G (7) → I (9) → L (12): +2, +3 

B (2) → E (5) → M (13): +3, +8  (Not follow)​
Option (d): FB – IE – LN

F + 3 → I, I + 3 → L
B + 3 → E, E + 9 → N (Follows)

Thus, correct option is (d).
