Answer and explanation

Correct answer: {1, 2, 3}

The region containing elements only in A is the set difference A \ B. The elements 4 and 5 occur in both A and B, so they belong to the intersection and must be removed from A. Removing them from {1, 2, 3, 4, 5} leaves {1, 2, 3}. Thus, option A represents the only-A region.
