- 198 = 2 × 9 × 11, so a number divisible by 198 is divisible by 2, 9, and 11.

- When digits are rearranged:

- Divisibility by 3 and 9 stays the same (since it depends on the sum of digits).

- Divisibility by 2 may change (last digit might not remain even).

- Divisibility by 6 depends on both 2 and 3; since 2 may change, 6 may not always apply.

- Divisibility by 66 (which is 2 × 3 × 11) can’t be assured (2 could change).

- So, only divisibility by 3 is guaranteed after rearrangement.

Correct answer: Option 1, 3.
