Answer:

C. second law of thermodynamics.

Explanation:

One of the consequences of this law is that there is no process of energy transformation 100% efficient. Some energy will always be lost in in the form of heat, which will be used to raise the temperature of some engine component, or its surroundings, and we will not be able to take advantage of it.
