The correct answer is:
A) 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 if performing that operation on any members of the set results in an outcome 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 always an integer.
