Solution
The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
The megaspore mother cell is diploid in nature. It undergoes meiosis to give rise to 4 haploid cells called megaspores. Three haploid cells degenerate and 1 survives to become the embryo sac. Meiosis is also called reductional division as the chromosome number is halved and the cell is converted from a diploid to haploid. Thus, the correct answer is option A.
