Verified by Experts

The correct Answer is:
B
• In a majority of flowering plants, one of the megaspores is functional while the other three degenerate.
• Functional megaspore develops into the female gametophyte (embryo sac). This method of embryo sac formation from a single megaspore is termed monosporic development.
• The nucleus of the functional megaspore divides mi totically to form two nuclei which move to opposite poles, forming the 2-nucleate embryo sac.
• Two more sequential mitotic nuclear divisions result in the formation of the 4-nucleate and later the 8-nucleate stages of the embryo.sac.
