2020 Phase-2 Human ReproductionGametogenesis - haploid and diploid stages Medium Question 38 of 116 in Human Reproduction

Select the correct option of haploid cells from the following groups:

A Primary spermatocyte, Secondary spermatocyte, Second polar body
B Primary oocyte, Secondary oocyte, Spermatid
C Secondary spermatocyte, First polar body, Ovum
D Spermatogonia, Primary spermatocyte, Spermatid

The answer is C.
