loader
C
Induced current flows to oppose motion
loader
D
Induced current remains equal to zero

The correct option is D Induced current remains equal to zero
Magnetic flux maybe flowing through the coil depending on the placement of magnet and coil. However, it doesn't change with time. Hence, no emf is produced.
