Letter triplet series KMO LNP MOQ NPR – UGC NET Question

The first letters are K, L, M and N, moving forward by one each time. The second letters are M, N, O and P, again moving forward by one. The third letters are O, P, Q and R, also advancing by one. The next term should therefore have letters O, Q and S, giving OQS.

Option A:
Option A is correct because it increases each letter of NPR by exactly one step: N→O, P→Q and R→S. This preserves the parallel +1 movement in all three positions. As it matches the transformation applied between each pair of successive terms, OQS is the proper continuation.

Option B:
Option B, OPR, keeps the first letter O but returns to P and R in the second and third positions. That fails to advance these positions as the pattern requires. Because not all three letters move forward, OPR does not fit the series.

Option C:
Option C, OQT, advances the third letter too far from R to T, a jump of two steps. The series shows only one-step shifts. This extra movement breaks the uniform transformation pattern, so OQT is not acceptable.

Option D:
Option D, ORU, changes the second and third letters unevenly and does not continue the simple +1 progression in all positions. It does not arise from applying the same shift to NPR. Therefore ORU cannot be the correct answer.
