$A Venn diagram with rectangle U and two overlapping circles A and B: 1,2 in A only, 3,4 in the overlap, 5,6 in B only, and 7,8,9,10 outside both circles$

In this same Venn diagram, what is A ∪ B (the union of A and B)?

{3, 4} — only the elements shared by both circles, ignoring everything else in A and B.

{7, 8, 9, 10} — the elements sitting outside both circles but still inside the rectangle.

{1, 2, 3, 4, 5, 6} — every element found in circle A or circle B (or both).
