Anemophily type of pollination is found in :

Options

A. Salvia
B. Bottle brush
C. Vallisneria
D. Coconut /DatePalm

Explanation

**Step-by-Step Solution:**

1. **Understand Anemophily**: Anemophily is a type of pollination that occurs when pollen is transferred from one flower to another by the wind. This method is common in certain plants that have adapted to utilize wind for reproduction.

2. **Identify Features of Anemophilous Flowers**:
- **Pollen Characteristics**: Flowers that undergo anemophily typically produce a large quantity of small-sized pollen grains. This is because the wind can easily carry these lightweight grains over distances.
- **Stigma Structure**: The stigma and style of these flowers are usually hairy. This structure helps in capturing the pollen grains that are carried by the wind.
- **Exposure to Wind**: The flowers must be well exposed to the wind to facilitate effective pollination. They are often positioned in such a way that they can easily catch the wind.

3. **Evaluate Examples of Plants**:
- **Salvia**: This plant has small, colored flowers and does not produce a large number of pollen grains. It is primarily pollinated by insects, not by wind.
- **Bottle Brush**: These flowers are bright red and are mainly pollinated by hummingbirds, not by wind.
- **Valisneria**: This aquatic plant relies on water currents for pollination, not wind.
- **Coconut and Date Palm**: Both of these plants are known to be anemophilous, as they produce large quantities of small pollen grains and are well adapted to wind pollination.

4. **Conclusion**: Based on the characteristics of anemophily and the examples discussed, the plants that exhibit anemophily are the coconut and date palm.

**Final Answer**: Anemophily type of pollination is found in coconut and date palm.
