The correct answer is B. A quasistatic process is a process that approaches an equilibrium state infinitely slowly. Under normal circumstances, a state of equilibrium includes three types: mechanical equilibrium, thermal equilibrium, and chemical equilibrium. This means that there are no potential or force differences either within or outside the system, the temperature is uniform, and the structure remains unchanged. Quasi-static processes are caused by potential differences or force differences, as well as differences in temperature and structure; they can exist everywhere, but in states that are extremely close to zero.
