The correct Answer is:
To analyze the given statements regarding sexual spores in pink mould, we will break down the assertion (A) and reason (R) step by step. ### Step 1: Understand the Assertion (A) The assertion states: "Sexual spores in pink mould are meiospores produced endogenously." - **Explanation**: In pink moulds, which are typically classified under the genus *Neurospora*, sexual spores (meiospores) are indeed produced through meiosis. These spores are formed within a structure called an ascus, which is an endogenous (inside) structure. This means that the assertion is true. ### Step 2: Understand the Reason (R) The reason states: "They develop flask-shaped fruiting body in sexual life cycle." - **Explanation**: In the sexual life cycle of pink moulds, the fruiting body is indeed flask-shaped, known as an ascocarp. This structure is where the sexual spores are produced. Therefore, the reason is also true. ### Step 3: Evaluate the Relationship Between A and R Now we need to determine if the reason accurately explains the assertion. - **Analysis**: While both the assertion and reason are true, the reason does not provide a direct explanation for the assertion. The assertion discusses the type of spores produced, while the reason describes the structure that produces these spores. Thus, the reason is not the correct explanation of the assertion. ### Conclusion Based on the analysis: - Both the assertion (A) and reason (R) are true. - However, the reason does not accurately explain the assertion. ### Final Answer The correct answer is: **Option B: Both assertion and reason are true, but reason is not the correct explanation of assertion.** ---
