Which set of numbers are whole numbers?

Whole numbers are defined as non-negative integers that include zero and all positive integers. The set of whole numbers starts from 0 and goes upwards without any fractions or decimals.

The set of numbers given in the correct choice consists of 0, 1, 2, 3, and 4, all of which fit the definition perfectly. There are no negative numbers or decimal values present in this group, confirming that all members of this set are whole numbers.

In contrast, the other sets contain elements that do not meet the whole number criteria. One set includes negative numbers, which are not whole numbers, another set comprises decimal numbers, disqualifying them as whole numbers, and while another set does contain whole numbers, it omits zero, which is also a fundamental part of the whole numbers. Thus, the first choice is the only set that encompasses all the necessary criteria to classify as whole numbers.
