Answer;

A. Movement of oxygen

Explanation;Carbon cycle is the cycle that controls the amount of carbon dioxide in the atmosphere. The cycle involves the movement of carbon between biosphere, atmospheres, hydrosphere and lithosphere.The carbon cycle is closely related to the cycling of oxygen throughout the environment and is tied to the process of photosynthesis.Photosynthesis by plants and dissolving of of carbon dioxide in the oceans remove carbon dioxide from the atmosphere. Respiration by plants, animals and microbes, combustion and thermal decomposition of limestone add carbon dioxide to the atmosphere.
