The answer is C.
CALCULATIONS and EXPLANATION
y = x²
x = +/- √y
The value of the square roots of y can either be negative or positive.
This is because when you square a negative number you will still get a positive square.
This implies that the value of x is not unique since we are not sure whether to take the negative value or the positive value.
For this reason this equation is not a relation.

Thank you for asking this question. Here is your answer:
The correct answer is Option D
Reason:
That is not possible because every function is a relation. It would not be possible if we call it something without a relation.
So make it easier for you we can say that every function is a relation but it is not important that every relation needs a function.
