what set of ordered pairs in the form of (x,y) does not represent a function of x

Answer:
I believe it's option C
Step-by-step explanation:
A function is a relation that does not contain two pairs with same first component.
option C
{(-1,2),(3,-2),(0,1),(3,5)} is not a function, since there are two pairs with the same first component i.e, 3
