Wind pollination is common in

Options

A. Legumes
B. Lilies
C. Grasses
D. Orchids

Explanation

**Step-by-Step Solution:**

1. **Understanding Wind Pollination**: Wind pollination, also known as anemophily, is a type of pollination where pollen is transferred from one flower to another by the wind.

2. **Characteristics of Wind-Pollinated Flowers**:
- **Color**: Flowers that are wind-pollinated are typically not brightly colored. They tend to be dull or white in color.
- **Nectar**: These flowers do not produce nectar, as nectar is usually associated with attracting insect pollinators.
- **Odor**: Wind-pollinated flowers lack a noticeable scent or odor.
- **Size**: The flowers are generally small in size, as they do not need to attract pollinators.
- **Pollen Production**: Wind-pollinated plants produce a large number of dry pollen grains to increase the chances of successful pollination.
- **Stigma**: The stigma of these flowers is often feathery to effectively catch airborne pollen.

3. **Analyzing the Options**:
- **Legumes**: These plants (like peas) have brightly colored flowers and are typically insect-pollinated, so they are not the correct answer.
- **Lilies**: Lilies also have bright flowers and are known for attracting insects, making them unsuitable for wind pollination.
- **Grasses**: Grasses are known for their small, dull flowers that do not attract pollinators, and they fit the characteristics of wind-pollinated plants.
- **Orchids**: Orchids usually have brightly colored flowers and are primarily pollinated by insects, thus they do not fit the criteria for wind pollination.

4. **Conclusion**: Based on the characteristics of wind-pollinated flowers and the analysis of the options, the correct answer is **grasses**.
