A particular species of plant produces light, non-sticky pollen in large numbers and its stigmas are long and feathery. These modifications facilitate pollination by

Options

A. insects
B. water
C. wind
D. animals

Explanation

To solve the question regarding the plant species that produces light, non-sticky pollen and has long, feathery stigmas, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Characteristics of the Pollen**:
- The pollen is described as light and non-sticky. This suggests that it is designed to be easily carried by air currents rather than adhering to surfaces.

2. **Examine the Stigma Structure**:
- The stigmas are long and feathery. This structure is typically adapted to capture pollen grains that are dispersed through the air.

3. **Consider the Pollination Mechanisms**:
- There are several mechanisms of pollination:
- **Insect Pollination**: Typically involves sticky pollen that adheres to insects.
- **Water Pollination**: Involves pollen that can float on water, usually not applicable to the characteristics given.
- **Wind Pollination**: Involves light, non-sticky pollen that can be carried by the wind, and stigmas that can catch airborne pollen.
- **Animal Pollination**: Similar to insect pollination, it usually involves sticky pollen.

4. **Match the Characteristics to the Pollination Mechanism**:
- Given the characteristics of the pollen (light and non-sticky) and the stigma (long and feathery), the most suitable mechanism for pollination is wind pollination.

5. **Conclusion**:
- Therefore, the modifications of the plant facilitate pollination by **wind** (anemophily).

### Final Answer:
The correct option is **C. Wind**.
