Why is a system’s work output limited?

AEntropy decreases with each stage of a system, causing a decrease in available entropy to carry out each stage.
BSystems tend to become less randomized over time, which causes spontaneous processes to no longer occur.
CEnergy is destroyed in each stage, causing the amount of available energy to decrease with each stage.
DEnergy is lost as heat in each stage, causing the amount of energy available to decrease with each stage.

Verified Answer :

The answer would be D. Energy is lost in the form of heat at each stage causing the amount of energy available to decrease at each stage. From the second law of thermodynamics, it is stated that entropy increases with time. As entropy increases the system now is more disordered causing more energy to be lost during a process some converted to work while some to other energy like heat.

Answer:

its D
