Explanation : The spermatogonia are diploid and have 46 chromosomes.

A primary spermatocyte completes the first meiotic division to form two equal, haploid cells called secondary spermatocytes, containing 23 chromosomes each.

The secondary spermatocytes undergo meiosis II to produce four equal, haploid spermatids which, in turn, produce 4 sperms.

Hence, 2 sperms are formed from the secondary spermatocyte.
