Explanation:

• Option A: Photosynthesis produces oxygen which organisms breathe, so this is a dependency.
• Option B: Photosynthesis makes sugar (glucose) which is used as food by organisms, so this is a dependency.
• Option C: Photosynthesis is mainly about producing food and oxygen, and reducing carbon dioxide (for global warming). It does not directly cure diseases.
• Option D: Photosynthesis takes in carbon dioxide, which helps reduce global warming (since CO₂ is a greenhouse gas), so this is a dependency.

Answer:

C. Helps cure disease
