Which statement is true about magnetic poles?

north and south poles repel each other.
north and south poles attract each other.
two south poles will attract each other.
two north poles will attract each other.

The correct answer is North & South poles attract each other. This is because opposites attract. If it were a north & north pole they'd repel each other, same if it were a south & south pole. This is because each magnetic field has a way of attracting two opposite poles (north to south, south to north).

Answer;

North and south poles attract each other.

Explanation;A magnet is a material that has an ability to produce magnetic fields.A magnet has two poles, north pole and a south pole. The north pole is the side which points north when a magnet is freely suspended on air, while south pole is the pole that points south. Based on the basic law of magnetism, like poles repel while unlike poles attract. Therefore, north pole attracts with a south pole, but repels another north pole. Two north poles repel while two south poles also repel.

An atom's smaller negative particles are at a distance from the central positive particles, so the negative particles are easier to move.
