if the normal force only acts perpendicular to a surface, what happens to the magnitude of the normal force on an object as the angle of the incline is increased?

The graph describes the motion of an object. the object moves with from a to b. it from b to c. it moves with from c to d.

For the car in the picture ,in which direction is the normal force? -into the screen -down -out of the screen -up
