If a = {1, 2, 3) and b = {1, 2, 3, 4, 5, 6, 7, 8) then aub
o {1, 2, 3)
o {1, 2, 3, 4, 5, 6, 7, 8)

The correct answer is  {1, 2, 3, 4, 5, 6, 7, 8}

Step-by-step explanation:

Let's recall that the union of two sets A and B is defined as the set of all the elements that are in set A or in set B. The union of two sets denotes as A ∪ B. In this case, all the elements of set A are included in set B. That's why the correct answer is set B  {1, 2, 3, 4, 5, 6, 7, 8}
