Solution

The correct answer is A. magnetism. This is because magnets have a north and a south pole. When like poles (north-north or south-south) are brought close to each other, they repel each other. When unlike poles (north-south or south-north) are brought close to each other, they attract each other. This can happen without the magnets physically touching each other.

On the other hand, springs (B) work through physical contact and displacement, friction (C) requires physical contact between surfaces, and gravity (D) can only attract objects, not repel them.
