    Correct Answer: C

    Solution :

    A fully organized polygonum type of embryosac is a 7 celled 8-nucleate structure. The cells of egg appratus and antipodal cells are haploid whereas the central cell is diploid i.e., contain two polar nuclei. Triploid endosperm is formed after triple fusion .i.e., fusion of second male gamete with polar nuclei.
