Answer 1

D

Explanation:

Flowing water has intrinsic kinetic energy that is harnessed to rotate the turbine. The turbine rotates hence gains mechanical energy because it is doing work. This work is used to rotate a dynamo of a generator which generates electricity. The mechanical energy is thus converted into electric energy by the dynamo. The electric energy is then carried by the power lines to the users.
