Answer 1

The correct option is A In A: cars 1 and 2 will come closer to each other

In B: 3 and 4 will move away from each other

In A, cars 1 and 2 will come closer to each other and in B, 3 and 4 will move away from each other.
Unlike poles of a magnet attract each other while like poles repel each other.
In case A: cars 1 and 2 are facing each other with opposite poles hence they get attracted.
In case B: cars 3 and 4 are facing each other with the same poles hence they get repelled.
