Solution

The correct option is B Diploid
The parenchyma cell of nucellus is the central part of the ovule containing the embryo sac and is diploid, and megaspore mother cell derived from the nucellus is the one which is going to form four megaspores with ploidy (n) by meiosis so again being a parent cell its ploidy is 2n.
Hence the correct answer is (B)
