Solution

The correct option is B 23
The number of chromosomes present in secondary spermatocyte in humans is 23. It is because the secondary spermatocytes are formed after the 1st meiotic division of diploid primary spermatocytes (having 46 chromosomes), hence they have haploid set of chromosomes, i.e., 23 in count.
