It would be number four - Mechanical energy is transformed to electromagnetic energy.

The Potential Energy in the coil is transformed into spinning Mechanical Energy which converts into Kinetic Energy which eventually shifts into Electrical Energy.

A generator converts mechanical energy into electrical energy.

Hence, 4. Mechanical energy is transformed to electromagnetic energy is the correct answer.
