Solution

The correct option is A Diamagnetic
Some substances when placed in a magnetic field are feebly magnetize in the opposite direction of the magnetic field. These substances when brought close to the pole of a powerful magnet are repelled away from the magnet. The body of a frog behaves like diamagnetic substance hence levitating it.
