Equus rests on

Options

A. Five digits
B. Four digits
C. Three digits
D. One digit

Answer

**Step-by-Step Solution:**

1. **Identify the Subject**: The question asks about "Equus," which is the genus of horses. Therefore, we are discussing horses specifically.

2. **Classify the Animal**: Horses belong to the class Mammalia. Within this class, there is a group known as ungulates, which are animals that have hooves.

3. **Understand Ungulate Classification**: Ungulates are further divided into two categories:
- **Artiodactyla**: Even-toed ungulates (e.g., cattle, giraffes, deer).
- **Perissodactyla**: Odd-toed ungulates (e.g., horses, zebras, rhinoceroses).

4. **Examine the Digits**:
- In **Artiodactyla**, there are two weight-bearing digits (even-toed).
- In **Perissodactyla**, there is only one weight-bearing digit (odd-toed), while the other digits are either reduced or absent.

5. **Conclusion**: Since horses belong to the Perissodactyla group, they rest on one digit. Therefore, the answer to the question is that Equus (horses) rests on **one digit**.
