Given the following:
U = {1, 2, 3, 4, 5, 6, 7, 8}
A = {3, 4, 8}
B = {1, 2, 3, 5, 8}
We are to construct a Venn diagram and place the elements in the proper regions.
Before we construct the Venn diagram, lets know a few things.
U is the universal set.
Set A and B are subset in the universal set.
Therefore the correct option is B.
