Options

A. entomophilous
B. hydrophilous
C. ornithophilous
D. anemophilous

Answer

To determine which of the given statements will be largest in size, we need to analyze each option based on their characteristics related to pollination and flower size.

### Step-by-Step Solution:

1. **Understanding the Options**:
- **Option A: Entomophilus** - This refers to plants that are pollinated by insects. Generally, insect-pollinated plants tend to have smaller flowers since they are adapted to attract specific insects.

- **Option B: Hydrophilus** - This refers to plants that are pollinated by water. These plants are often small and inconspicuous, as they rely on water currents for pollination.

- **Option C: Ornithophilus** - This refers to plants that are pollinated by birds. These plants typically have large, colorful flowers with plenty of nectar to attract birds. They often have long tubular structures to accommodate bird pollinators.

- **Option D: Anemophilus** - This refers to plants that are wind-pollinated. Wind-pollinated plants usually have small flowers that are not very conspicuous since they do not need to attract pollinators.

2. **Comparing Flower Sizes**:
- **Entomophilus**: Small flowers.
- **Hydrophilus**: Small and inconspicuous flowers.
- **Ornithophilus**: Large flowers, colorful, with a lot of nectar.
- **Anemophilus**: Small flowers.

3. **Conclusion**:
Based on the characteristics of the flowers associated with each type of pollination, we can conclude that **Ornithophilus** has the largest flowers among the options provided.

### Final Answer:
The largest in size is **Option C: Ornithophilus**.
