The set of integers is:

And at the same time contain the set of whole and natural numbers then 15 is also in the integers.

And the set of rational numbers is:

And at the same time contain the set of whole, natural numbers and integers then 15 is also in the rational numbers.

Now 15 is not an irrational number because don't have a infinity growth of numbers after the decimal point and neither complex because isn't in the options.
