Let's break it down step by step:

Given Words: FAM, MAN, XTG, TEM, UUQ

- Consonants: Replace with immediate *preceding* letter (e.g., F?E).

- Vowels: Replace with immediate *succeeding* letter (e.g., A?B).

Let's process each word:

- FAM:

- F (C) ? E

- A (V) ? B

- M (C) ? L

- New Word: EBL

- MAN:

- M (C) ? L

- A (V) ? B

- N (C) ? M

- New Word: LBM

- XTG:

- X (C) ? W

- T (C) ? S

- G (C) ? F

- New Word: WSF

- TEM:

- T (C) ? S

- E (V) ? F

- M (C) ? L

- New Word: SFL

- UUQ:

- U (V) ? V

- U (V) ? V

- Q (C) ? P

- New Word: VVP

Now, let's check for vowels in each new word

(Vowels: A, E, I, O, U)

- EBL: Has E (Yes)

- LBM: No vowels

- WSF: No vowels

- SFL: No vowels

- VVP: No vowels

Only EBL has at least one vowel.
