The best example of a closed system from the given options is **a sealed jar of salad dressing**.
In a sealed jar, no matter can enter or exit, which characterizes a closed system. The other examples involve interactions or exchanges with their surroundings (e.g., the bowl of punch can have ingredients added or removed, the human body exchanges matter and energy with the environment, and the atmosphere of a planet can interact with space).
