B

Explanation:

Primary spermatocytes undergo meiosis for the production of sperm. In meiosis one parental cell produce four daughter cells with half the number of chromosomes in each cell.

As given here; primary spermatocytes having a 4n number of chromosomes so after meiosis, each sperm cells would have a 2n number of chromosomes, because each daughter cell contain half the number of chromosome as compared to parental cell, so 4n parental cell will produce 2n daughter cell in meiosis.
