a) the state with the maximum disorder
b) the same state in which it began
c) the state with lowest possible energy
d) the state with the lowest possible energy consistent with the state of maximum disorder
D) is the best selection
The system will end in the state with the lowest possible energy and highest entropy (disorder).
D - as an analogy consider yourself and your bedroom (or kitchen etc). If "left to change spontaneously" or in other words having no external forces/controling factor appied what would be the state of your room (kitchen) - utter chaos and it is what took the least amount of energy.
D. is the correct answer with regard to The third law of thermodynamics on Entropy.
