Answer and explanation

Correct answer: {1, 3, 5}

The difference A − B contains elements that are in A but are not in B. Starting with A = {1, 2, 3, 4, 5}, remove the elements 2 and 4 because they belong to B. The elements left are 1, 3, and 5, so A − B = {1, 3, 5}. The order of elements in a set does not matter.
