Solution

The correct option is C diploid
The formation of megaspores from the megaspore mother cell is the process that results in the generation of reduction of ploidy from diploid to haploid. If this process fails i.e. meiosis doesn’t occur during megasporogenesis, then the reduction of the chromosome number won’t happen, and the embryo sac formed from the megaspore will have diploid nuclei and not haploid nuclei.
