Select the triad which follows the same pattern as that followed by the two triads given below. Both triads follow the same pattern.
NQ-KO-IL
FI-CG-AD

The correct option is JM-GK-EH.

Let's analyze the pattern followed by the letters in each triad by looking at their positions in the English alphabet (A = 1, B = 2, C = 3, ..., Z = 26).
We examine the first given triad: NQ - KO - IL.
Let us write down the alphabetical positions of each letter in the pairs:
• N = 14, Q = 17
• K = 11, O = 15
• I = 9, L = 12

Let's analyze the relationship between the first letter of each pair in the triad (N → K → I):
• N (14) → K (11) represents a shift of -3.
• K (11) → I (9) represents a shift of -2.
Now let's analyze the second letter of each pair in the triad (Q → O → L):
• Q (17) → O (15) represents a shift of -2.
• O (15) → L (12) represents a shift of -3.

Let's verify this pattern with the second given triad: FI - CG - AD.
The alphabetical positions are:
• F = 6, I = 9
• C = 3, G = 7
• A = 1, D = 4

Looking at the first letter transition (F → C → A):
• F (6) → C (3) represents a shift of -3.
• C (3) → A (1) represents a shift of -2.
Looking at the second letter transition (I → G → D):
• I (9) → G (7) represents a shift of -2.
• G (7) → D (4) represents a shift of -3.

Thus, the pattern for the letters in the triad 1stPair - 2ndPair - 3rdPair is:
• 1st letter of 2ndPair = (1st letter of 1stPair) - 3
• 1st letter of 3rdPair = (1st letter of 2ndPair) - 2
• 2nd letter of 2ndPair = (2nd letter of 1stPair) - 2
• 2nd letter of 3rdPair = (2nd letter of 2ndPair) - 3

Let's apply this pattern to the correct option: JM - GK - EH.
The alphabetical positions of the first pair (JM) are J = 10, M = 13.
• The first letter of the second pair should be J (10) - 3 = G (7).
• The second letter of the second pair should be M (13) - 2 = K (11).
So, the second pair is GK, which matches the option.

Now, let's find the third pair:
• The first letter of the third pair should be G (7) - 2 = E (5).
• The second letter of the third pair should be K (11) - 3 = H (8).
So, the third pair is EH, which also matches the option.

Therefore, the triad JM-GK-EH perfectly follows the same pattern.
