Answer:
Both A and B
Explanation:
The second law of thermodynamics has different formulations, some of them are those mentioned in options A and B.
The fact that the entropy of an isolated system always increases is something that comes from the idea of irreversible processes, for example we see that the particles of a gas expand in volume to occupy the total space of the container, but we never see that all the particles come together in a single corner of the container. This is why some authors refer to entropy as a measure of disorder in a system, and that eventually the simple fact that time passes leads to a "disorder" or an increase in entropy.
In addition, the second law of thermodynamics is usually mentioned in terms of the energy flow, which in spontaneous events is observed to always flow from hot objects or systems to cold ones and never the other way around.
