Nonnegative numbers are defined as numbers that are either positive or zero. This means that they include all positive numbers along with zero itself. The correct choice accurately captures this definition, stating that nonnegative numbers consist of all numbers including zero.

In contrast, the other options do not adequately describe nonnegative numbers. For instance, all negative numbers are explicitly excluded from the category of nonnegative numbers. Whole numbers typically refer to nonnegative integers, which do not include fractions, but this definition is more limited than what is needed. Lastly, fractional numbers can be either positive or negative; thus, referencing fractional numbers alone does not encompass the complete set of nonnegative numbers, particularly since it would exclude zero.
