The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Photosynthesis**: Photosynthesis is the process by which plants convert light energy into chemical energy, producing sugars and oxygen as byproducts. This process is essential for plant growth and energy production. 2. **Identifying Key Nutrients**: Among the nutrients mentioned (carbon, nitrogen, iron, and magnesium), we need to determine which one has a direct role in the photosynthesis process. 3. **Role of Chlorophyll**: Chlorophyll is the green pigment in plants that plays a crucial role in photosynthesis by trapping light energy. The structure of chlorophyll includes a cyclic tetrapyrrole head and a long phytol tail. 4. **Magnesium's Role**: In the structure of chlorophyll, magnesium is a central atom that coordinates with the four pyrrole rings of the cyclic tetrapyrrole head. This coordination is essential for the chlorophyll molecule to function effectively in capturing light energy. 5. **Conclusion**: Since magnesium is directly involved in the structure of chlorophyll, it is the nutrient that has a direct relationship with photosynthesis. While iron is also important for chlorophyll synthesis, magnesium is the key nutrient that is part of the chlorophyll structure itself. **Final Answer**: Magnesium is the nutrient that has a direct relationship with photosynthesis. ---
