The correct answer is based on the horsepower. That it is mainly one mechanical (Hydraulic) hp or one Electrical hp. Let's take an example to be able to understand the steps in order to answer this question correctly.
If one mechanical hp =1 hp(I) = 745.699872 W
& If one electrical hp= 1 hp(E) = 746 W
In addition to this, mechanically 745 W, electrically 746W
It was originally defined as 550 foot-pounds per second (ft-lb/s). A power level of 1 hp is approximately equivalent to 746 watt s (W) or 0.746 kilowatt s (kW). To convert from horsepower to watts, multiply by 746. 746 watts = 1 Horse power and this is the law of electricity . So the answer is C . 746 W
