To use front-end rounding, we look at the digit in the tens place, which is 0 in this case. Since 0 is less than 5, we round down the ones place to 0. Therefore, the estimated number is 4,900. Front-end rounding means adding or subtracting from the leftmost digit of a number. In this case, the leftmost digit is 1. Since the next digit is less than 5, we keep the leftmost digit as is (1) and drop all the other digits. This gives us 1,000. Adding this to the original number gives us 5,006. The only option that is closest to this estimation is C, which is 4,900.
