The correct Answer is:
To solve the question regarding the assertion and reason about the circulatory system of cockroaches, we will follow these steps: ### Step-by-Step Solution: 1. **Understand the Assertion**: The assertion states that the circulatory system of the cockroach does not contain any capillaries. - **Evaluation**: This statement is true. Cockroaches have an open circulatory system, which means their blood (hemolymph) flows freely in the body cavity and does not utilize capillaries like in closed circulatory systems. 2. **Understand the Reason**: The reason provided is that the blood of the cockroach does not contain any respiratory pigment. - **Evaluation**: This statement is also true. Cockroach blood lacks hemoglobin, which is the primary respiratory pigment found in many other animals. Instead, their blood is colorless and does not transport oxygen in the same way. 3. **Determine the Relationship**: Now we need to assess whether the reason given is a correct explanation of the assertion. - **Analysis**: While both statements are true, the absence of capillaries in the cockroach's circulatory system is not directly explained by the absence of respiratory pigments in its blood. The two facts are related to the physiology of the cockroach, but one does not explain the other. 4. **Conclusion**: Based on the evaluations: - Both the assertion and reason are true. - However, the reason does not provide a correct explanation for the assertion. 5. **Select the Correct Option**: Given the evaluations, the correct option is: - (b) If both Assertion & Reason are True but Reason is not a correct explanation of the Assertion.
