Solution

The correct options are
A The needle attracts objects made of magnetic materials.
B The needle gets deflected when it is brought near a magnet.
D The needle comes to rest in the North-South direction.
The needle of a magnetic compass attracts or repels other magnets, and is also deflected in their presence. It attracts or repels magnetic materials and comes to rest in the North-South direction in the absence of magnets. Thus, it shows all the properties that a bar magnet possesses. Therefore, it can be proven that it is made up of a magnetic substance.
