A Correct answer
Explanation

If the rounded number is 10400 (nearest hundred), the minimum original number is 10350. This is because any number from 10350 to 10449 rounds to 10400. The lower bound (10350) is exactly halfway, which rounds up. 10300 would round to 10300, and 10250 would round to 10200.
