Select the triad that follows the same pattern as that followed by the two triads given below. Both triads follow the same pattern.
FB-ID-KM
JF-MH-OQ​

FB-ID-KM
JF-MH-OQ​

Logic: 1st letter = +3, +2 

2nd letter= +2, +9

F +3 → I, I +2 → K
B +2 → D, D +9 → M

J +3 → M, M +2 → O
F +2 → H, H +9 → Q

Similarly,

M +3 → P, P +2 → R
I +2 → K, K +9 → T

Thus, correct option is (a).
