Answer and explanation

Correct answer: {4, 6}

The difference B − C contains elements that are in B but not in C. Set B is {2, 4, 6}; among these, 2 also belongs to C and must be removed. The elements 4 and 6 are not in C, so they remain. Therefore B − C = {4, 6}. The set A is extra information here and does not affect the requested difference.
