It is the set of all the elements in the universal set that are not in given set. A. complement B. difference C. entersection D. union

Explanation:

Let's say we had the universal set of all natural numbers {1,2,3,4,...}

Then let's further say that a subset of this is the set of positive even numbers {2,4,6,8,...}

The complement of the second set would be the set of positive odd numbers {1,3,5,7,...} which is the stuff not found in the second set mentioned, but it's found in the universal set. This is one example of the complement of a set.
