Which of the following functions will return the symmetric difference between two sets, x and y?x | yx ^ yx & yx – y

The function that will return the symmetric difference between two sets, x and y, is x ^ y.

Here's a step-by-step explanation:

1. The symmetric difference between two sets is the set of elements that are in either of the sets but not in their intersection.

2. In Python, the caret (^) operator is used to find the symmetric difference of two sets.

3. So, if you have two sets x and y, you can find their symmetric difference by using the expression x ^ y.

4. The other operators mentioned have different functions. The pipe (|) operator is used for union of two sets, the ampersand (&) operator is used for intersection, and the minus (-) operator is used for difference.

So, the correct answer is x ^ y.
