Please assist me with the following question. Work shown in detail would be greatly appreciated

5. In the Set Cover problem, discussed in Chap. 5 of the textbook, you are given as input a finite set B of elements and a list of subsets of those elements, S Sm C B. (This problem was discussed in lecture in Section C.) We call set B the ground set. We can think of each set Si as "covering" the elements it contains. The problem is to choose subsets S from this list whose union is equal to B (so that together, the subsets "cover" all the elements of B). The number of chosen subsets should be as small as possible. We call the set of chosen subsets a minimum cover of the ground set. Consider the following set cover instance, which we are representing graphically. 5.
