Which of the following ways are suitable for increasing food production? I) Agrochemical based agriculture.
II) Organic agriculture.
III) Genetically engineered crop-based agriculture.
Choose the correct option.

Options

A. I and II
B. I and III
C. II and III
D. I, II and III

Answer

To determine which methods are suitable for increasing food production, we will analyze each option provided:

### Step-by-Step Solution:

1. **Agrochemical Based Agriculture**:
- This method involves the use of synthetic fertilizers and pesticides to enhance crop yield.
- The main goal is to maximize production by providing essential nutrients and controlling pests that can damage crops.
- **Conclusion**: This method is effective in increasing food production.

2. **Organic Agriculture**:
- Organic agriculture focuses on growing crops without synthetic chemicals, using natural fertilizers (like compost) and organic pest control methods.
- While the primary aim is to enhance the nutritional value of food and promote environmental sustainability, it also aims to increase crop yield through organic means.
- **Conclusion**: This method is also suitable for increasing food production.

3. **Genetically Engineered Crop-Based Agriculture**:
- This approach involves modifying the genetic makeup of crops to enhance desirable traits such as pest resistance, drought tolerance, and increased nutritional content.
- Genetically engineered crops can lead to higher yields and more efficient food production.
- **Conclusion**: This method is effective in increasing food production as well.

### Final Answer:
All three methods (I, II, and III) are suitable for increasing food production. Therefore, the correct option is **1, 2, and 3**.
