Whole numbers can be defined as?

Whole numbers are defined as all non-negative integers, which include zero and all the positive integers (1, 2, 3, etc.). This definition clarifies that whole numbers do not encompass negative numbers or fractions. By focusing on the inclusion of zero as the smallest whole number and the fact that whole numbers are free of decimal points or fractional parts, option B accurately captures the essence of what whole numbers are.

The other choices do not align with the definition of whole numbers. Negative numbers, fractions, and terms related to prime and composite numbers all fall outside the parameters of whole numbers, as they either involve negative values, parts of a whole, or classifications of integers rather than the comprehensive category of non-negative integers. Thus, the selection of option B represents a precise understanding of whole numbers.
