Which of the following is a non-SI unit of power commonly used to rate electrical equipment?

Explanation:
Power can be described in different units, and in many contexts, especially for motors and generators, a traditional unit called horsepower is still used. Horsepower is not part of the SI system, and it provides a familiar way to express how much work the equipment can do over time. One horsepower is defined as about 746 watts, with mechanical horsepower close to 745.7 watts and electrical horsepower often cited as 746 watts. This makes horsepower a non-SI unit that’s commonly used to rate electrical equipment. The other options are SI units or units tied to energy or potential, not to a power rating.
