Which stage immediately follows meiosis I in spermatogenesis?

In spermatogenesis, the first meiotic division (meiosis I) converts a diploid primary spermatocyte into two haploid cells called secondary spermatocytes. The stage that follows meiosis I, therefore, is the secondary spermatocyte. After that, each secondary spermatocyte undergoes meiosis II to form spermatids, which then mature into spermatozoa. So other stages don’t fit because spermatogonium is the mitotic precursor before meiosis, and spermatids and spermatozoa come after meiosis II and the subsequent spermiogenesis.
