A car dealership needs a program to store information about the cars for sale. For each car, they want to keep track of the following information number of doors (2 or 4), whether the car has air conditioning, and its average number of miles per gallon. Which of the following is the best design?
a. Use classes: Doors, Airconditioning, and MilesPerGallon, each with a subclass Car.
b. Use a class Car, with subclasses of Doors, Airconditioning, and MilesPerGallon.
c. Use a class Car with three subclasses: Doors, Airconditioning, and MilesPerGallon.
d. Use a class Car, with fields: numDoors, hasAir, and milesPerGallon.
e. Use four unrelated classes: Car, Doors, Airconditioning, and MilesPerGallon.

In this topic, the option d, which is "Use a class Car, with fields: numDoors, hasAir, and milesPerGallon" is right because the flag, if air-conditioned, of its numbers of doors, was its average kilometers per gallon, qualities of either an automobile, in which each one is a basic value so that they're being fields of a class of cars.
