The correct answer is

PRM

Track the first, second and third letters of the terms separately using alphabet positions (A = 1, …, Z = 26).

First letters: L (12), M (13), N (14), O (15) – each moves +1, so the next is P (16). Second letters: N (14), O (15), P (16), Q (17) – each moves +1, so the next is R (18).

Third letters: I (9), J (10), K (11), L (12) – each moves +1, so the next is M (13). Therefore the missing term is PRM.

Check: within every term the pattern is +2 from the first to the second letter and –5 from the second to the third (L→N→I, M→O→J, N→P→K, O→Q→L); for PRM, P (16) + 2 = R (18) and R (18) – 5 = M (13), which fits.

Hence, PRM.
