Maize is

Options

A. Cleistogamous
B. Anemophilous
C. Entomophilous
D. Hydrophilous.

Answer

To answer the question "Maize is," we need to analyze the options provided and determine the correct type of pollination that maize undergoes. Here’s a step-by-step solution:

### Step 1: Understand the Options
We are given four options:
1. Callistochemus
2. Anemophilus
3. Entomophilus
4. Hydrophilus

### Step 2: Analyze Each Option
- **Callistochemus**: This refers to a type of self-pollination seen in certain plants that can propagate through non-opening flowers. This is not applicable to maize.

- **Anemophilus**: This term refers to wind pollination. In this process, pollen is distributed by the wind, which is a characteristic of maize and many other plants, especially in the grass family.

- **Entomophilus**: This type of pollination occurs through insects. While many plants rely on insects for pollination, maize does not.

- **Hydrophilus**: This is a rare type of pollination where pollen is distributed through water. This is not relevant to maize.

### Step 3: Identify the Correct Answer
From the analysis, we can conclude that maize is primarily pollinated by wind, making the correct answer **Anemophilus**.

### Conclusion
Thus, the correct answer to the question "Maize is" is:
**Option 2: Anemophilus.**
