Water in the soil available to plants is :

Options

A. Gravitational water
B. Capillary water
C. Hygroscopic water
D. None of these

Answer

To answer the question "Water in the soil available to plants is:", we need to understand the different types of water present in the soil and their availability to plants.

### Step-by-Step Solution:

1. **Identify Types of Soil Water**:
- There are three main types of water present in the soil: gravitational water, capillary water, and hygroscopic water.

2. **Define Gravitational Water**:
- Gravitational water is the water that drains through the soil due to gravity. It is not retained in the soil and is typically not available for plant uptake.

3. **Define Hygroscopic Water**:
- Hygroscopic water is the water that is tightly bound to soil particles and forms a thin film around them. This water is not available to plants because it cannot be absorbed due to its strong adhesion to the soil particles.

4. **Define Capillary Water**:
- Capillary water is the water that fills the spaces between non-colloidal soil particles and is held by capillary forces. This type of water is available for plants as it can be absorbed by their roots.

5. **Conclusion**:
- Since capillary water is the fraction of water that is available for plants to absorb, the correct answer to the question is **capillary water**.

### Final Answer:
The water in the soil available to plants is **capillary water**.
