What should come in place of the question mark (?) in the given series based on the English alphabetical order?

EHO, HJP, KLQ, ? , QPS

Given: EHO, HJP, KLQ, ? , QPS

Logic: 1st letters + 3, 2nd letters + 2, 3rd letters + 1

E + 3 = H
H + 3 = K
K + 3 = N
N + 3 = Q

So, the first letter of the missing term is N.

H + 2 = J
J + 2 = L
L + 2 = N
N + 2 = P

So, the second letter of the missing term is N.

O + 1 = P
P + 1 = Q
Q + 1 = R
R + 1 = S

So, the third letter of the missing term is R.

So, the missing term is NNR

Thus, the correct option is (d) NNR
