Answer:
b. A
Step-by-step explanation:
If A ∩ B= ∅, this means that there are no elements of A that are shared with B
The complement of B, is all elements within U that are not in B. As we already stated that the elements of A are not within B, this would mean that the complement of B would have the elements of A within it.
Due to this, A ∩ Complement of B = A
