Answer 1

The correct answer is (a) It is heading inwards, i.e. the direction is towards inside of the car

Easiest explanation: When you curl your wrist in the direction in which the tires are moving then you will find that the thumb is pointing outwards. That is outwards the body of the car. This phenomenon is also observed in rainy seasons. When cars travel on the roads, the water is thrown outside from the tires, due to moment.
