Based on the law of conservation of energy, which statement is false?

The choices, which the user did not provided are these:
A. Energy is lost when machines do not work right.
B. We can not add more energy to the universe.
C. We can not destroyed the energy that exist in the universe.
D. Energy changes from one form to another.
 All the statements give above are true with the exception of option A, which is FALSE. Therefore, A is the correct answer.
The law of conservation of energy states that energy can neither be created nor destroyed, it can only be transformed from one form to another form. This implies that, energy is already present in the environment, man can not add to it neither can man take away from it, man can only change the energy from one type to another type when work is done. This means that, even when machine do not work right, the quantity of energy in the system will still be constant.
