The correct Answer is:
**Step-by-Step Solution:** 1. **Identify the Question**: The question asks for the hardest plant product among the given options: lignin, cutene, sporopolynin, and subrine. 2. **Understand Each Option**: - **Lignin**: A complex organic polymer found in the cell walls of many plants, providing rigidity and resistance to decay. - **Cutene**: A water-repellent substance found in the cuticle of plants, composed of esters of fatty acids. - **Sporopolynin**: A highly resistant and chemically stable compound found in the outer walls of plant spores and pollen grains. - **Subrine**: A complex organic molecule found in the cell walls of certain plants, contributing to their protective barrier. 3. **Evaluate the Hardness**: - Among the options, sporopolynin is noted for its extreme hardness and resistance to degradation. It is specifically mentioned as the toughest of all plant products. - While lignin, cutene, and subrine are tough and serve protective roles, they do not match the hardness of sporopolynin. 4. **Conclusion**: Based on the evaluation, the hardest plant product is **sporopolynin**. 5. **Final Answer**: The correct answer is **sporopolynin**. ---
