The correct Answer is:
To analyze the statements given in the question, we will evaluate each statement step by step. ### Step 1: Evaluate Statement A **Statement A:** Male gametophyte in gymnosperms is highly reduced. - In gymnosperms, the male gametophyte is indeed highly reduced. - The male gametophyte develops from the microspore and is represented by the pollen grain, which consists of only a few cells. - This reduction is a characteristic feature of both gymnosperms and angiosperms, where the gametophyte generation is minimized compared to the sporophyte generation. **Conclusion for Statement A:** True. ### Step 2: Evaluate Statement B **Statement B:** Megasporophylls are compactly arranged in Cycas. - Cycas is a genus of gymnosperms, specifically a type of cycad. - In Cycas, the male reproductive structures (microsporophylls) are indeed compactly arranged to form a male cone. - However, the megasporophylls, which are the female reproductive structures, are not compactly arranged. Instead, they are loosely arranged, forming a structure that is not compact like the male cones. **Conclusion for Statement B:** False. ### Final Conclusion: - Statement A is true, while Statement B is false. Therefore, the answer to the question is that Statement B is incorrect. ---
