Answer:
D. Is used to describe the class
Step-by-step explanation:
If we create a class, we must describe our processes, we could use this class to run different operations in programming.
For example:
We're going to create the class CAR, then we will create attributes and functions.
class car{
//attributes
//With attribute, we described our class car, we could add more definitions for example doors, motor, or high.
public int wheels;
public string model;
//With functions, we can create an action for our class car, in this case, our car can run and stop.
//functions
public void run;
public void stop;
}
