Answer

Brief Explanations:

The law of conservation of energy states that energy cannot be created or destroyed, only transferred or transformed. For machines, the total energy input equals the total energy output (including any energy lost as heat or other forms due to inefficiencies). Option A is incorrect as machines don't create energy. Option B is wrong because energy is conserved and not completely consumed. Option D is false since the law of conservation of energy is always upheld.

Answer:

C. Energy transferred to a machine equals energy transferred from it.
