What should come in place of ? in the given series based on the English alphabetical order?
JMQ ILP HKO GJN ?

The correct option is FIM.

To find the missing term in the series JMQ, ILP, HKO, GJN, ?, let us analyze the pattern of each letter position in the consecutive terms.

First, let's write down the position of each letter in the standard English alphabetical order (A = 1, B = 2, ..., Z = 26):
J = 10, M = 13, Q = 17
I = 9, L = 12, P = 16
H = 8, K = 11, O = 15
G = 7, J = 10, N = 14

Now, let us examine the pattern for each of the three letter positions across the series:

1. First Letter of each term:
J (10) ⇒ I (9) ⇒ H (8) ⇒ G (7) ⇒ ?
The pattern is a decrease of 1 in each step (10 - 1 = 9; 9 - 1 = 8; 8 - 1 = 7).
Following this pattern, the next first letter must be 7 - 1 = 6, which corresponds to the letter F.

2. Second Letter of each term:
M (13) ⇒ L (12) ⇒ K (11) ⇒ J (10) ⇒ ?
The pattern is a decrease of 1 in each step (13 - 1 = 12; 12 - 1 = 11; 11 - 1 = 10).
Following this pattern, the next second letter must be 10 - 1 = 9, which corresponds to the letter I.

3. Third Letter of each term:
Q (17) ⇒ P (16) ⇒ O (15) ⇒ N (14) ⇒ ?
The pattern is a decrease of 1 in each step (17 - 1 = 16; 16 - 1 = 15; 15 - 1 = 14).
Following this pattern, the next third letter must be 14 - 1 = 13, which corresponds to the letter M.

Combining these three results, the next term in the series is FIM.
