A) The chromosomes in secondary spermatocytes consist of two chromatids; the ones in the spermatid consist of only one chromatid.
B) The chromosomes in a secondary spermatocyte consist of homologous chromosomes; the ones in the spermatid consist of two chromatids.
C) The chromosomes in the secondary spermatocyte consist of one chromatid; the ones in the spermatid consist of two chromatids.

Secondary spermatocytes are formed by meiosis I which results in two haploid cells, each consisting of two chromatids. During the second meiotic division, the two chromatids separate, resulting in four haploid cells, each consisting of a single chromatid. These cells are known as spermatids. Thus, the chromosomes in a secondary spermatocyte consist of two chromatids while the ones in a spermatid consist of only one chromatid. Therefore, option A is correct.
