The diagram below shows the magnetic field pattern near two magnetic poles, P P\,P and QQQ, and a point X X\,X situated on the vertical axis of symmetry directly above the region between the poles.
A small plotting compass is placed at point XXX.
Which row in the table correctly identifies poles P P\,P and QQQ, and the direction of the north pole of the plotting compass needle at XXX?

|---|---|---|---|
| A | South | South | Downwards |
| B | North | North | Upwards |
| C | South | South | Upwards |
| D | North | North | Downwards |
