Answer 1

Zero belongs to the following sets of real numbers:

- Whole numbers: Whole numbers include all non-negative integers, which means they include 0.
- Integers: Integers include all positive and negative whole numbers, as well as zero.
- Rational numbers: Rational numbers are numbers that can be expressed as the quotient of two integers (where the denominator is not zero). Since 0 can be expressed as 0/1, it is also a rational number.

So the correct option from the ones provided is:

**whole numbers, integers, and rational numbers**
