The statement that best supports the student's claim that the type of energy transformation in a hydroelectric dam is mechanical to electrical is:
B. The turbine must turn for electricity to flow from the generator to the power lines.
This option highlights the mechanical energy from the moving water turning the turbine, which then drives the generator to produce electrical energy.
