He comes . . . . . . . . a car. A. at B. by C. with D. on

The correct answer is: C. with

The preposition “with” is used to indicate that someone is traveling in a vehicle. In this case, the person is traveling in a car.

The other options are incorrect because they do not accurately describe the relationship between the person and the car.

• The preposition “at” is used to indicate a location. In this case, the person is not at a car, but rather in a car.
• The preposition “by” is used to indicate a means of transportation. In this case, the person is not traveling by car, but rather in a car.
• The preposition “on” is used to indicate a surface. In this case, the person is not on a car, but rather in a car.
