C. Useful energy out of a system is always less than the energy input of that system.
Explanation:
The correct statement of the given options is that useful energy out of a system is always less than the energy input of that system.
This is in compliance with the third law of thermodynamics which states that "energy transformation in a system is not 100% efficient".
- At every stage energy is usually lost when it is transformed from one form to another.
- There is no machine that is 100% efficient.
- A machine that is 100% efficient will convert all the useful energy in it to do work and even more.
- In system energy is usually lost as a result of heat and to overcome friction.
- This reduces the amount of energy out of a system.
