Assertion: Abdominal muscles is related with respiration in animals.
Reason: Relaxation of abdominal muscles draws in air.

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 assertion and reason question, we will analyze both the assertion and the reason step by step.

### Step 1: Understand the Assertion
The assertion states that "abdominal muscles are related to respiration in animals."
- **Explanation**: The abdominal muscles play a role in the process of respiration. During breathing, these muscles can assist in changing the pressure within the thoracic cavity, which is essential for inhalation and exhalation.

### Step 2: Understand the Reason
The reason provided is that "relaxation of abdominal muscles draws in air."
- **Explanation**: When the abdominal muscles relax, it allows the diaphragm to move downwards, which decreases the pressure in the thoracic cavity. This pressure change causes air to be drawn into the lungs.

### Step 3: Analyze the Relationship
Now we need to determine if the reason correctly explains the assertion.
- The assertion is correct because abdominal muscles do indeed play a role in respiration.
- The reason is also correct because the relaxation of abdominal muscles contributes to the inhalation process by allowing the diaphragm to function effectively.

### Conclusion
Since both the assertion and the reason are correct, and the reason provides a correct explanation for the assertion, we conclude that both statements are true.

### Final Answer
The answer is option A: Both the assertion and reason are correct, and the reason is the correct explanation of the assertion.
