A car starts from rest and accelerates along a straight, horizontal road. The car's engine provides a constant driving force, while the car experiences an air resistance force that increases with its speed. Eventually, the car reaches a constant maximum speed. Which row in the table correctly describes the velocity and the acceleration of the car during this motion?
| Velocity of the car | Acceleration of the car | |
|---|---|---|
| A | increases then decreases | positive then negative |
| B | increases then decreases | positive then zero |
| C | increases then constant | positive then negative |
| D | increases then constant | positive then zero |
