Answer

To solve the question regarding the stomach of ruminants and identify which part is missing in camels, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of Ruminant Stomach**:
- Ruminants have a specialized stomach that is divided into four distinct parts: Rumen, Reticulum, Omasum, and Abomasum.
- Each part has a specific function related to the digestion of food, particularly cellulose and protein.

2. **Identify the Functions of Each Part**:
- **Rumen**: The first chamber, responsible for the fermentation and digestion of cellulose with the help of microorganisms.
- **Reticulum**: The second chamber, which stores large food particles and aids in the mixing of food.
- **Omasum**: The third chamber, which absorbs water and nutrients from the food.
- **Abomasum**: The fourth chamber, similar to the human stomach, responsible for protein digestion.

3. **Analyze the Question**:
- The question states that in camels, one part of the ruminant stomach is missing. We need to determine which one it is.

4. **Recall Information About Camels**:
- Camels are classified as ruminants, but they have a slightly different stomach structure compared to typical ruminants like cows.
- It is known that camels lack the omasum.

5. **Select the Correct Answer**:
- Based on the information gathered, the part that is missing in camels is the **Omasum**.
- Therefore, the correct answer is **(d) Omasum**.

### Final Answer:
The part of the stomach that is missing in camels is (d) Omasum.
