Which of the following letter-number clusters will replace the question mark (?) in the given series to make it logically complete?
HKP22, ILQ31, JMR40, KNS49, ?

Given: HKP22, ILQ31, JMR40, KNS49, ?

Logic: Letters are increasing + 1 and number is increasing + 9 place.

For, letter

H + 1 = I, I + 1 = J, J + 1 = K, K + 1 = L

K + 1 = L, L + 1 = M, M + 1 = N, N + 1 = O

P + 1 = Q, Q + 1 = R, R + 1 = S, S + 1 = T

For, number 

22 + 9 = 31, 31 + 9 = 40, 40 + 9 = 49, 49 + 9 = 58

So, the missin term is LOT58.

Thus, correct option is (b).
