Solution

The correct option is D 8
In meiosis, each mother cell divides to produce 4 daughter cells. Thus 32 spermatids will be produced from 32/4, i.e., 8 spermatocytes. This calculation is based on the assumption that all the cell produced after meiosis are functional. This may not be the case always. For example, in the case of angiosperms, ovule develops from a single megaspore called functional megaspore and three megaspores of the four megaspores produced after meiosis in megaspore mother cell degenerate. In this case, each meiosis event gives rise to only one functional haploid egg cell.
So, the correct answer is option B.
