The correct Answer is:
To analyze the assertion and reason provided in the question, we will break down the statements and evaluate their truthfulness step by step. ### Step-by-Step Solution: 1. **Understanding the Assertion**: - The assertion states that "Blood of cockroach is colourless haemolymph with no respiratory pigments." - **Evaluation**: This statement is true. Cockroaches have a fluid called haemolymph, which is indeed colorless and lacks respiratory pigments like hemoglobin that are found in the blood of vertebrates. 2. **Understanding the Reason**: - The reason states that "Respiration in Cockroach occurs through diffusion in haemolymph." - **Evaluation**: This statement is incorrect. While cockroaches do respire, they do not rely on haemolymph for gas exchange. Instead, they have a tracheal system that allows direct contact of air with body tissues for respiration. The tracheae transport oxygen directly to the tissues, making the statement about diffusion in haemolymph incorrect. 3. **Conclusion**: - Since the assertion is true and the reason is false, the correct answer to the question is that "Assertion is true but reason is wrong." ### Final Answer: **Assertion is true but reason is wrong.** ---
