C. Generator and motor.
In case of generator mechanical energy is converted into electrical energy
But in motor, electrical energy is changed into mechanical energy.
An electrolyzer is a device that converts mechanical energy to chemical energy by using electricity to split water into hydrogen and oxygen gases.
Assuming that you're talking about a wind-powered electrical generator (such as a "wind farm"), the energy conversion is from mechanical to electrical. When the wind blows on the blades of the mill it rotates them, creating mechanical energy. This mechanical energy is used to power the electrical generator inside the mill, creating electrical energy out of mechanical energy.
b) a generator. Generators create alternating current (AC) by converting mechanical energy into electrical energy through electromagnetic induction.
In a coal burning steam generator, the energy transformations involve the chemical energy stored in coal being converted into thermal energy through combustion. The thermal energy produced heats water to create steam, which then drives a turbine to generate mechanical energy. Finally, the turbine's mechanical energy is transformed into electrical energy by the generator.
The four main sources of heat are the sun, geothermal energy from the Earth's core, friction from mechanical processes, and chemical reactions such as combustion.

Nothing "creates" energy. The chemical energy in gasoline can be converted to electrical energy by burning the gasoline in an internal combustion engine that's connected to a generator.

Mechanical and chemical digestion are not the same.
when your teeth grind food is it chemical or mechanical
Depending on what you're referring to, you may have this completely backwards. A motor's efficiency is fairly high. A generator's efficiency at converting chemical/kinetic/mechanical energy to electric energy is at best around 50%.
