The ruminants are included in the order :

Options

A. Sirenia
B. Proboscidea
C. Perissodactyla
D. Artiodactyla

Answer

**Step-by-Step Solution:**

1. **Understanding Ruminants**: Ruminants are animals that have a specialized digestive system with four compartments in their stomach. These compartments are the rumen, reticulum, omasum, and abomasum.

2. **Examples of Ruminants**: Common examples of ruminants include sheep, cows, buffaloes, and giraffes. These animals have a unique feeding process where they chew their food partially, swallow it, and then regurgitate it to chew it again.

3. **Identifying the Order**: The question asks which order ruminants belong to. Ruminants are classified under the order Artiodactyla. This order is characterized by even-toed ungulates, meaning they have an even number of toes on their feet.

4. **Clarifying Other Orders**: The transcript mentions other orders such as Perissodactyla (odd-toed animals), Proboscidea (elephants), and Sirenia (aquatic animals like dugongs and sea cows). However, these are not related to ruminants.

5. **Conclusion**: Therefore, the correct answer to the question is that ruminants are included in the order Artiodactyla.

**Final Answer**: Ruminants are included in the order Artiodactyla.
