I think that it is A, 180..
The union of two sets<span> A and B is the </span>set<span> of elements which are in A, in B, or in both A and B. In symbols, . For example, if A = {1, 3, 5, 7} and B = {1, </span>2<span>, 4, 6} then A ∪ B = {1, </span>2<span>, 3, 4, 5, 6, 7}.
The intersection of 2 sets depict elements that appear in both sets (all elements in B that also appear in A). In the Venn diagram, the intersection of the sets are always in the middle of both sets. I attached a photo to show you the perfect example of the intersection of sets.
I hope it helps :)</span>
