The correct answer is a. respiration.
While photosynthesis (b) is the process by which plants absorb carbon dioxide from the atmosphere and convert it into oxygen and glucose, respiration (a) is the process by which organisms, including plants and animals, convert glucose and oxygen into carbon dioxide, water, and energy, thus reintroducing carbon dioxide into the atmosphere.
Evaporation (c) does not play a role in carbon cycling. Therefore, "all of the above" (d) is not correct.
