The correct response is:
An operation performed on members of that set will result in a member of the same set.
In mathematical terms, a set is considered "closed" under a certain operation (such as addition, subtraction, multiplication, or division) if performing that operation on any members of the set always produces a result that is also a member of the same set. For example, the set of integers is closed under addition because the sum of any two integers is also an integer.
