Explanation:

Let’s break it down:

- Option 1: NSY — If you look at the letters, N, S, Y, check their positions in the alphabet: N (14), S (19), Y (25). The jump is +5, then +6.

- Option 2: TYE — T (20), Y (25), E (5). Here, it's +5, then looping back to the start of the alphabet (Y to E is +6, using modulo 26 logic).

- Option 3: PUB — P (16), U (21), B (2). That’s +5, then +7 if you count from U looping back around to B.

- Option 4: LQW — L (12), Q (17), W (23). Now, +5, then +6.

Now here’s the thing: NSY, TYE, and LQW all follow the same +5, then +6 alphabetical pattern (with wrapping as needed). PUB, on the other hand, goes +5, then +7.

So the odd one out is:

Option 3: PUB
