I cant quite figure out how to tell what is the independent and dependent variable of this equation

In the followingsituation, state whether two variables are related in a way that might be described by a function. Ifso, identify the independent and dependent variables.

You walk through a used car lot and list the price and model year of each car you see.

A. The situation can be described by a function. The dependent variable is the model and the independent variable is the price.

B. The situation can be described by a function. The dependent variable is the price and the independent variable is the model.

C.The situation can be described by a function. There is a dependentvariable, but no independent variable. The dependent variable is the price

D.The situation cannot be described by a function.
