Select the pair which follows the same pattern as that followed by the two set of pairs given below. Both pairs follow the same pattern.
JKK : KFH
HVO : IQL

The correct option is OOP : PJM.

To understand why this is the correct answer, let's analyze the alphabetical positions of the letters in the given pairs, where A = 1, B = 2, ..., Z = 26.
Let us first write down the numerical positions of all the letters involved in the pattern:

J = 10, K = 11, F = 6, H = 8
V = 22, O = 15, I = 9, Q = 17, L = 12

Now, let us analyze the relationship between the letters in the given pairs:

First Set: JKK : KFH
1st letter: J (10) → K (11) : 10 + 1 = 11 (+1 shift)
2nd letter: K (11) → F (6) : 11 - 5 = 6 (-5 shift)
3rd letter: K (11) → H (8) : 11 - 3 = 8 (-3 shift)

Second Set: HVO : IQL
1st letter: H (8) → I (9) : 8 + 1 = 9 (+1 shift)
2nd letter: V (22) → Q (17) : 22 - 5 = 17 (-5 shift)
3rd letter: O (15) → L (12) : 15 - 3 = 12 (-3 shift)

Thus, the common pattern followed by both sets of pairs is:
1st letter: +1 shift
2nd letter: -5 shift
3rd letter: -3 shift

Now, let us verify this pattern with the correct option, OOP : PJM:
O = 15, P = 16, J = 10, M = 13
1st letter: O (15) → P (16) : 15 + 1 = 16 (+1 shift)
2nd letter: O (15) → J (10) : 15 - 5 = 10 (-5 shift)
3rd letter: P (16) → M (13) : 16 - 3 = 13 (-3 shift)

Since the pair OOP : PJM follows the exact same shift pattern (+1, -5, -3), it is the correct answer.
