Solution
The correct option is B diamagnetic
Frogs, like everything around and inside us, are made up of millions and billions of atoms. Each of these atoms contains electrons that whizz around a central nucleus, but when atoms are in a magnetic field, the electrons shift their orbits slightly. These shifts give the atoms their own magnetic field so when a frog is put in a very strong magnetic field, it is essentially made up of lots of tiny magnets. Frogs move towards the weaker magnetic region. Diamagnetic materials moves from stronger magnetic field region to weaker magnetic field region. Therefore body of the frog behaves as diamagnetic.
