A. attract.
B. repel also.
C. may attract or repel.

A. attract

Explanation:

A magnetic pole is region at the ends of a magnet where the external magnetic field has the strongest magnitude.

Unlike kinds of magnetic poles attract each other. This is due to magnetic flux likes at the poles of the magnet.

The North magnetic pole has flux lines that flow/point outwards while South magnetic pole has flux lines that flow/point inwards, hence, when they are brought close to one another, they attract.

This is shown in the diagrams below.
