Solution

The correct option is A $F_{1}$ provided by the friction between the tyres and the road.
When the car moves along a circular path, it needs a centripetal force acting inwards to compensate for the centrifugal force acting outwards. This force is provided by the frictional force between tyres and road which will act towards the center of circular motion. The weight of the car and people in it compensate for the normal reaction on the car due to the road.
