Based on the English alphabetical order, three of the following four are alike in a certain way and thus form a group. Which one does not belong to the group?

To find which option doesn't belong, we need to check the pattern in how the letters move in alphabetical order.

Let's find the alphabetical position of each letter and see the differences:

Option	Letters	Positions	Pattern of differences
1	O-U-L-Q	15→21→12→17	+6, -9, +5
2	N-T-M-P	14→20→13→16	+6, -7, +3
3	E-K-D-G	5→11→4→7	+6, -7, +3
4	K-Q-J-M	11→17→10→13	+6, -7, +3

---

Looking at the patterns:

Options 2, 3, and 4 all follow the same pattern: +6, -7, +3

• First letter to second letter: move forward by 6 positions
• Second letter to third letter: move backward by 7 positions
• Third letter to fourth letter: move forward by 3 positions

Option 1 follows a different pattern: +6, -9, +5

Since three options (2, 3, 4) follow the same movement pattern and Option 1 doesn't, Option 1 (OULQ) does not belong to the group.
