Answer:

B. Energy and matter can enter and leave

Explanation:

An open system is one that can exchange matter and energy with its surroundings.

The atmosphere is the layer of gas that is surrounding a celestial body, it has properties that are related to its chemical composition and physical state. To maintain its properties, external processes and interactions are required that help maintain or alter its characteristics. Among these processes we can highlight the temperature, pressure and movement. These processes, in which exchanges occur, are what make the atmosphere not a closed system.
