The image depicts the generation of electricity through hydroelectric means. Which statement BEST describes the manner in which electricity is being generated in this process?

A) Electrical energy causes hydrolysis of the water passing through the dam.
The oxygen and hydrogen gas power the turning of the turbine blades,
which then power the generator.

B) Water passing through the dam turns the turbines, which then powers the
generator. The generator converts mechanical energy into electricity,
which is transmitted through power lines.

C) Falling water over the dam powers a generator which creates steam to turn
the turbines. The turbines convert thermal energy into electrical energy to
be transmitted through the power lines.

D)Flowing water through the dam quickly becomes heated, converting to steam. Steam turns the turbine blades, which can power the generator. The generator provides electrical energy to the transmission lines.
