Answer 1

The correct option is A $46$

Spermatocytes are a type of male gametocytes in human. There are two types of spermatocytes: primary spermatocytes and secondary spermatocytes. Primary spermatocytes are diploid cells which consist of 46 chromosomes in each cell. Each secondary spermatocyte contains 23 chromosomes because they are haploid cells. Thus the correct answer is option A, 46.
