The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Problem**: Continuous cultivation of crops on the same land depletes the soil of its nutrients. This is a common issue in agriculture, leading to reduced soil fertility. 2. **Identifying Solutions**: To replenish the lost nutrients in the soil, we need to add certain substances. The two main types of substances that can be added are manure and fertilizers. 3. **Defining Manure**: Manure is an organic material that is rich in nutrients. It can be made from animal excreta, decomposed plant material (like dry leaves), and dead organisms. These materials decompose and enrich the soil with essential nutrients. 4. **Defining Fertilizers**: Fertilizers are chemical substances that contain specific nutrients required for plant growth. They are usually in the form of chemical salts and provide essential ions and nutrients directly to the soil. 5. **Conclusion**: By adding manure and fertilizers to the soil, we can restore its nutrient content and improve its fertility, making it suitable for continuous crop production. 6. **Final Answer**: Therefore, the correct answer to the question is that "manure and fertilizers" are added to the soil to replenish its lost nutrients. ---
