Solution

## The correct option is C With a bar magnet with its poles marked.We know that like poles of a magnet repel each other and unlike poles attract each other. Take a magnet which has its poles (north and south) marked and it is brought near to the front side of the car. If the front side of the toy car gets attracted to the north pole of the given magnet then it can be inferred that the south pole of the bar magnet inside the car is facing the front of the car. If the toy car gets repelled, it can be inferred that north pole of the bar magnet inside the car is facing the front of the car.
