The correct answer is {1, 2, 3, 4, 5, 6, 7, 8}.
To find the union of sets A and B, you need to combine all the elements from both sets without duplication.
Set A = {1, 2, 3, 4, 5}
Set B = {5, 6, 7, 8}
To find the union, you simply combine all the elements from both sets:
A union B = {1, 2, 3, 4, 5, 6, 7, 8}
