Please explain how to came to the answer, thank you.

When a car goes around a circular curve on a level road,
no frictionalforce is needed because the car simply follows theroad.
the frictionalforce of the road on the car increases when the car's speeddecreases.
the frictionalforce of the road on the car increases when the car's speedincreases.
the frictionalforce of the road on the car increases when the car moves to theoutside of the curve.
there is no netfrictional force because the road and the car exert equal andopposite forces on each other.

Explanation / Answer

Answer is thefrictional force of the road on the car increases when the car'sspeed increases Since the frictional force is directly proportional tospeed
