The correct Answer is:
To solve the assertion and reason statement question, we will analyze both the assertion and the reason step by step. ### Step-by-Step Solution: 1. **Understanding the Assertion**: - The assertion states that "Distal centriole acts as a basal granule." - The distal centriole is located in the neck of the sperm and is responsible for giving rise to the axial filament of the tail. This means it plays a crucial role in the structure of the sperm tail and can be considered as a basal granule from which the tail structure arises. 2. **Evaluating the Reason**: - The reason states that "Distal centriole induces cleavage in egg." - Cleavage refers to the series of cell divisions that occur after fertilization. The proximal centriole, not the distal centriole, is responsible for inducing cleavage in the egg. Therefore, this statement is incorrect. 3. **Conclusion**: - Since the assertion is true (the distal centriole does act as a basal granule), but the reason is false (the distal centriole does not induce cleavage), we conclude that the assertion is true, and the reason is false. 4. **Final Answer**: - The correct option is that the assertion is true, and the reason is false.
