A sealed jar of salad dressing is the example of a closed system. In this context, a closed system does not exchange matter with its surroundings, while it can exchange energy. The other options either involve exchanges of matter (like the atmosphere of a planet, a bowl of punch, or the human body) or are not strictly closed.
