• A. 64
• B. 128
• C. 192
• D. 32

Answer 1

Answer: (D)

32

The nucellus in the gymnosperm is made up of a mass of diploid cells and is contained in the ovule. One of its cells, the microsporocyte, produces 4 megaspores by meiosis. The endospermic cells will, therefore, have 32 chromosomes as it is haploid.

So, the correct answer is option D.
