Select the letter-cluster from among the given options that can replace the question mark (?) in the following series.NYQ, KWP, HUO, ESN, ?

Let's trace the pattern for each letter in the cluster across the series:First Letter: N $\to$ K $\to$ H $\to$ E $\to$ ?N (14) - 3 = K (11)K (11) - 3 = H (8)H (8) - 3 = E (5)E (5) - 3 = B (2)Second Letter: Y $\to$ W $\to$ U $\to$ S $\to$ ?Y (25) - 2 = W (23)W (23) - 2 = U (21)U (21) - 2 = S (19)S (19) - 2 = Q (17)Third Letter: Q $\to$ P $\to$ O $\to$ N $\to$ ?Q (17) - 1 = P (16)P (16) - 1 = O (15)O (15) - 1 = N (14)N (14) - 1 = M (13)Combining these gives the cluster BQM.
