Round 4.567 to the nearest whole number.

Rounding a number to the nearest whole number involves looking at the digit in the first decimal place to determine how to round it. In this case, the number is 4.567.

The digit in the ones place is 4, which is the starting point for rounding. Next, we examine the digit immediately to the right of the decimal point, which is 5. According to rounding rules, if this digit is 5 or greater, we round up the whole number by 1. Since the digit is indeed 5, we increase the 4 in the ones place to 5.

Therefore, rounding 4.567 to the nearest whole number results in 5, making it the correct answer.
