  1. Water
  2. Carbon monoxide
  3. Oxygen
  4. Nitrogen
  5. Carbon monoxide
Explanation
Answer: C, Oxygen. Oxygen is released as a byproduct of photosynthesis in plants.

Key Takeaway: Photosynthesis is a process that converts carbon dioxide and water into organic compounds such as sugars using sunlight as energy. Oxygen is released as a byproduct of this process, in the same way that carbon dioxide is released by humans as a byproduct of aerobic respiration. Nitrogen and carbon monoxide are not involved in either process.
