C. photosynthesis and respiration

Plants and other autotrophs release O2 into the atmosphere during photosynthesis, while animals and decomposers consume O2 during cellular respiration. The other choices are hydrologic processes (evaporation, precipitation), not the biological steps of the oxygen cycle.
