Zero belongs to the following sets of real numbers:
- Whole numbers (which include all non-negative integers: 0, 1, 2, 3, ...)
- Integers (which include all whole numbers and their negative counterparts: ..., -3, -2, -1, 0, 1, 2, 3, ...)
- Rational numbers (which include all numbers that can be expressed as a fraction of two integers, where the denominator is not zero: for example, 0 can be expressed as 0/1, 0/2, etc.)
Zero does not belong to the set of natural numbers (which generally start from 1 in most definitions).
Based on these observations, the correct option from your responses is:
whole numbers, integers, and rational numbers.
