Assertion: Chloragogen cells are considered analogous to the liver of vertebrates.
Reason: Because it is concerned with the storage of reserve food, deamination of proteins, formation of urea, etc.

Options

A. If both Assertion and Reason are true and the Reason is the correct explanation of the Assertion.
B. If both Assertion and Reason are true, but the Reason is not the correct explanation of the Assertion.
C. If Assertion is true, but Reason is false.
D. If both Assertion and Reason are false.

Answer

To solve the question regarding the assertion and reason about chloragogen cells, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "Chloragogen cells are considered analogous to the liver of vertebrates."
- Chloragogen cells are specialized cells found in annelids, particularly in earthworms, and they perform functions similar to those of the liver in vertebrates.

2. **Understanding the Reason**:
- The reason provided is that chloragogen cells are "concerned with the storage of reserve food, deamination of proteins, formation of urea, etc."
- This indicates that chloragogen cells have metabolic functions similar to those of the liver, including storing glycogen (reserve food), processing proteins (deamination), and producing urea.

3. **Evaluating the Truth of the Assertion**:
- The assertion is true because chloragogen cells do have functions that are analogous to the liver, such as detoxification and metabolism.

4. **Evaluating the Truth of the Reason**:
- The reason is also true, as chloragogen cells are indeed involved in the storage of food and the processing of proteins and urea formation.

5. **Determining the Relationship**:
- Since both the assertion and reason are true, and the reason provides a correct explanation for the assertion, we conclude that the reason is a valid explanation for the assertion.

### Final Conclusion:
- Both the assertion and reason are true, and the reason correctly explains the assertion.
