This is another tricky question. All of the provided answers are actually units which do relate to power so this questions does not actually have a correct answer. A watt can also be called a Newton-meter per second and they are both units of power. A watt is the same thing that tells you how bright your lightbulbs will be.

Horse power is also a unit of power, seeing as it has the word power right in its name, this is not a tricky answer. It is usually in a physics course where you learn about power and the different categories of units of power.

Power has different units. It can be written as Watt or as Newton-meter per second. Power is also measured in horsepower. The Joule-second is a unit of energy. It is also often used as a plank constant. Power is basically the property of an object to do something. One watt of power is the resulting force exerted when one joule is burnt in 1 second.

In another context, the power is also a property of the direct current. It is calculated by multiplying the voltage with the current. Therefore, there are a number of different units of power that are employed in different situations, according to the context.

Since Power is Work/time, Joule per second fits
