The correct answer is C. Atmosphere, lithosphere, biosphere, and hydrosphere.
Explanation
Earth is a planet that belongs to the solar system. The earth is composed of several elements that constantly interact forming a system, that is to say, it is composed of interrelated and dependent parts, so if one of the parts changes, the others are modified, altering the entire system. The main parts of the Earth are its subsystems that are the lithosphere, the atmosphere, and the hydrosphere. These subsystems fulfill specific functions that allow the development of life on Earth. These subsystems are related. Each system has a particular function, the atmosphere contains oxygen and carbon dioxide; the hydrosphere contains all forms of water on earth, and the lithosphere is made up of mineral salts and support for living things. At the same time, these three subsystems allow the existence of the biosphere, that is, the subsystem referring to all forms of life on Earth. So, the correct answer is C. Atmosphere, lithosphere, biosphere, and hydrosphere.
