Solution

The correct options are
B perpendicular to the coil
C away from the coil
As shown in the figure, the coil behaves as a north pole in the direction facing the magnet. Hence, the coil and magnet repel each other. The force on the magnet is in upward direction which is perpendicular to the coil.
