Explanation:

Given:
The number is a 4-digit number.
When reversed, it gives a smaller number.

Analysis:
To find the smallest 4-digit number that, when reversed, gives a smaller number, we need to consider the position of digits in a 4-digit number.

Steps to Find the Smallest Number:
- Start with the smallest 4-digit number, which is 1000.
- Reversing 1000 gives 0001, which is not a valid 4-digit number.
- Move to the next number, which is 1001.
- Reversing 1001 gives 1001, which is equal to the original number.
- The next number is 1100.
- Reversing 1100 gives 0011, which is a smaller number.
- Hence, the smallest 4-digit number that, when reversed, gives a smaller number is 1100.
Therefore, the correct answer is option B (1100).
