Anemophily occurs in
(a) Salvia
(b) Vallisneria
(c) Coconut
(d) Bottle Brush

Options

A. Salvia
B. Vallisneria
C. Coconut
D. Bottle Brush.

Answer

To determine which of the given plants exhibits anemophily (wind pollination), we will analyze each option step by step.

### Step-by-Step Solution:

1. **Understanding Anemophily**:
- Anemophily refers to the process of pollination where pollen is transferred by wind. This type of pollination is characterized by light, non-sticky pollen grains that can be easily carried by air currents.

2. **Analyzing Option (a) Salvia**:
- Salvia is known to require pollinators (like insects) for its pollination process. This indicates that it does not rely on wind for pollination, thus it does not exhibit anemophily.

3. **Analyzing Option (b) Vallisneria**:
- Vallisneria is a water plant that primarily uses water for its pollination process, known as hydrophily. Therefore, it does not exhibit anemophily.

4. **Analyzing Option (c) Coconut**:
- Coconut trees are well-known for their anemophilous characteristics. They produce light and feathery pollen that can be carried by wind, making them a prime example of wind pollination.

5. **Analyzing Option (d) Bottle Brush**:
- The Bottle Brush plant typically relies on birds for pollination, indicating that it is not anemophilous but rather relies on animal pollination (entomophily).

6. **Conclusion**:
- After analyzing all options, the only plant that exhibits anemophily is **Coconut** (option c).

### Final Answer:
**(c) Coconut**
