Horse is

Options

A. Digitigrade
B. Unguligrade
C. Plantigrade
D. None of the above

Answer

To determine the type of locomotion exhibited by a horse, we will analyze the given options step by step.

### Step-by-Step Solution:

1. **Understanding Digitigrade Locomotion**:
- Digitigrade locomotion is characterized by organisms that walk on their toes, using only the digits (toes) for movement.
- Examples of digitigrade animals include dogs and cats.
- **Conclusion**: Horses do not walk on their toes, so this option is incorrect.

2. **Understanding Unguligrade Locomotion**:
- Unguligrade locomotion refers to animals that walk on their hooves, which are essentially modified tips of their toes.
- Horses are a prime example of unguligrade locomotion, as they use their hooves for walking.
- **Conclusion**: Since horses exhibit this type of locomotion, this option is correct.

3. **Understanding Plantigrade Locomotion**:
- Plantigrade locomotion involves walking on the entire foot, including the heel and toes.
- Humans and bears are examples of animals that exhibit plantigrade locomotion.
- **Conclusion**: Horses do not walk on their entire foot, so this option is also incorrect.

4. **Evaluating "None of the Above"**:
- Since we have identified the correct locomotion type as unguligrade, the option "none of the above" is also incorrect.

### Final Answer:
The correct option is **Unguligrade** (Option B).
