Select the triad which follows the same pattern as that followed by the two triads given below. Both triads follow the same pattern.
JM-HK-FI
MP-KN-IL2594

The correct option is PS-NQ-LO.

To understand the pattern, let us first note the alphabetical positions of the letters:
A = 1, B = 2, C = 3, D = 4, E = 5, F = 6, G = 7, H = 8, I = 9, J = 10, K = 11, L = 12, M = 13, N = 14, O = 15, P = 16, Q = 17, R = 18, S = 19, T = 20, U = 21, V = 22, W = 23, X = 24, Y = 25, Z = 26.

Let us analyze the pattern in the first given triad, JM - HK - FI:

For the first letters of each term (J, H, F):

$J\Rightarrow H\Rightarrow F$

$10-2=8$

$8-2=6$

Thus, the first letters decrease by 2 at each step.

For the second letters of each term (M, K, I):

$M\Rightarrow K\Rightarrow I$

$13-2=11$

$11-2=9$

Thus, the second letters also decrease by 2 at each step.

Additionally, within each pair, the second letter is 3 positions ahead of the first letter:

$M-J=13-10=3$

$K-H=11-8=3$

$I-F=9-6=3$

Let us verify this same pattern with the second given triad, MP - KN - IL:

For the first letters (M, K, I):

$M\Rightarrow K\Rightarrow I$

$13-2=11$

$11-2=9$

For the second letters (P, N, L):

$P\Rightarrow N\Rightarrow L$

$16-2=14$

$14-2=12$

Checking the difference within each pair:

$P-M=16-13=3$

$N-K=14-11=3$

$L-I=12-9=3$

Now, let us test the correct option, PS - NQ - LO:

For the first letters (P, N, L):

$P\Rightarrow N\Rightarrow L$

$16-2=14$

$14-2=12$

This matches the first-letter pattern.

For the second letters (S, Q, O):

$S\Rightarrow Q\Rightarrow O$

$19-2=17$

$17-2=15$

This matches the second-letter pattern.

Checking the difference within each pair:

$S-P=19-16=3$

$Q-N=17-14=3$

$O-L=15-12=3$

This matches the internal difference pattern.

Therefore, the triad PS-NQ-LO follows the exact same pattern.
