Given three sets A, B, C. Which expression represents the elements that are in C, but not in A or B?
Answer: A
We want elements that are in C and are not in A and not in B.
The set of elements in A or B is A ∪ B.
To find the elements in C that are not in this union, we perform a set difference.
The correct expression is C - (A ∪ B).
