I like to think of the domain and range as coordinates, so think of the domain as the x value, or the input, and the range as the y value, or the output. 

So, b wouldn't work because of what I just explained. 

C could be defined as slope. 

And d won't work because this would be defined as a function. 

So the only answer left would be A. The inputs of a relation (but just know that domain is also the input of a function)

I hope I helped!

Answer:

A. The inputs of a relation
