The most appropriate choice for an example of a perfectly closed system among the options given is:
**A cup of tea with a lid on it; energy transfer takes place with the cup and the surroundings, but no matter leaves the tea.**
In this scenario, while energy can be transferred (such as heat), no matter is escaping, which aligns with the definition of a closed system in thermodynamics.
