The answer is the third choice, which is (10,1). The reason why is because (10,-2) is a point in the given function set. We cannot list x = 10 more than once.

In visual terms, the relation would fail the vertical line test if the relation had (10,-2) and (10,1) at the same time in the set. The other points mentioned (choice 1, choice 2, choice 4) are allowed because those x values haven't been mentioned yet.
