What is the mechanical efficiency of the turbine? Plese tell me.

According to me, (A) is Right Answer.

Power is not produced by the turbine its produce by the generator.

So if you think to answer it must be wrong.

Mechanical efficiency = Power available at the rotor shaft/Power produced by the runner.

Mechanical efficiency = Shaft power (actual power produced by the turbine)/Runner power (energy actually supplied by the turbine).

So why not Answer(A).

Mechanical efficiency = Shaft power(work available at the turbine)/Runner power(wheel).
