A cup of water is left on the roof of a car. When the car begins to move, the cup does not move forward with the car. Instead, it falls off. What happened to the cup of water?

• a. The cup accelerated backward as the car accelerated forward, so the cup fell off the car. 
• b. An unbalanced force caused the cup to move with the car, but gravity caused it to fall. 
• c. The upward force on the cup increased as the car moved forward, so the cup fell. 
• d. Inertia kept the cup from moving while the car moved forward.
