What is the contribution of Cornelius van Niel to the understanding of photosynthesis?
  1. He discovered the process of photosynthesis
  2. He demonstrated that photosynthesis is a light-dependent reaction
  3. He showed that H₂S is the hydrogen donor for photosynthesis
  4. He proved that O₂ evolved from carbon dioxide during photosynthesis
