As the roller coaster car travels from Point A to Point B, typically, the car is descending, which means it is losing height. As it loses height, the gravitational potential energy decreases and is converted into kinetic energy as the car speeds up.

Therefore, the correct answer is:

**D. The car's gravitational potential energy is transformed into kinetic energy.**
