Answer: The best choice would be: Rational Numbers
The 4 numbers in this list only all belong to the set of rational numbers. All of the other sets can be crossed off.
First, 102.9 is not an integer, so we can't select choice A.
Second, 0 is not a natural number, so we can't select choice B.
Third, none of the numbers are irrational, so we can't select choice D.
The only choice left is choice C - rational numbers.
