When a car goes around a banked circular curve at the proper speed speed for the banking angle, what force cause it to follow the circular path?
A) the friction force from the road
B) the normal force from the road
C) gravity
D) No force causes the car to do this because the car is traveling at constant speed and therefore has no acceleration.

The normal force from the road is responsible for providing the centripetal force necessary for the car to follow the circular path when it is traveling at the proper speed for the banking angle. This is because the normal force can be resolved into components, one of which points towards the center of the circular path, acting as the centripetal force.
