I believe the correct answer to be:
primary spematocyte produce 2 secondary spermatocyte is first meiosis and then each secondary spermatocyte make 2 spermatids.
So, the total number of cells or sperms produced by each primary spermatocyte = 4.
feel free to leave a comment down below for any further query. good rating would be appreciated if you find my answer helpful. thank you.
