Options

A. Irrigation canal
B. Drip irrigation
C. Sprinkler system
D. Pulley system

Answer

To determine the best irrigation technique for Karan's fields in Rajasthan, where there is a severe shortage of water, we can analyze the available options step by step:

### Step-by-Step Solution:

1. **Identify the Water Situation**: Karan lives in Rajasthan, a region known for its water scarcity. This means that any irrigation method chosen must be efficient in water usage.

2. **Evaluate Irrigation Techniques**:
- **Irrigation Canal**: This method involves large channels that transport significant amounts of water. Given the water shortage in Rajasthan, this method is not suitable as it can lead to wastage of water.

- **Drip Irrigation**: This technique delivers water directly to the roots of plants in a controlled manner, drop by drop. This method minimizes water wastage and is highly efficient, making it ideal for regions with limited water supply like Rajasthan.

- **Sprinkler System**: This system sprays water over the crops, simulating rainfall. While it is more efficient than canals, it still results in more water wastage compared to drip irrigation, especially in windy conditions.

- **Pooling System**: This method involves collecting water in a circular pool and distributing it to the fields. It can be inefficient as it may not deliver water directly to the plants and can lead to evaporation losses.

3. **Conclusion**: After evaluating all the options, drip irrigation stands out as the best choice for Karan's fields. It conserves water effectively and ensures that crops receive the necessary moisture without wastage.

### Final Answer:
The best irrigation technique for Karan's fields in Rajasthan is **Drip Irrigation**.
