The example of a perfectly closed system among the options provided 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 case, while energy can be exchanged (for instance, heat transfer), matter does not leave the system, which aligns with the definition of a closed system.
