Step-by-step explanation:
None of them
A has (5, 13) and (5,17) That's 2 y values for the same x. You can't have that. A fails the vertical line test.
B has two y values for x = - 3. The two values are (-3,-1) and (-3,1). Both values eliminate B as an answer.
C fails because -1 has 2 y values (-4,52) and (-4,?) We can't see the bottom, but it is another value. There is an x value we cannot see that has 45 as an answer along with -7 for x. That's fine.
If there is a D answer, you almost have to choose it. There isn't much choice.
