Answer: D. {12, 13, 14, 15, 16, 17, 18}

Step-by-step explanation:

The union of two sets A and B is the set of elements which are in A, in B, or in both A and B, without repetition.

In this case, the union of the sets G and H will be the set of elements in G= {12, 14, 16, 18}  and then the set of elements in H= {13, 15, 17, 18}, excluding those that already were in G, which in this case is the number 18.

Then:

G ∪ H={12, 13, 14, 15, 16, 17, 18}
