(D) To determine the ploidy of the given structures:$1$. Spermatid: Haploid $(n)$$2$. Secondary oocyte: Haploid $(n)$$3$. Primary spermatocyte: Diploid $(2n)$$4$. Ovum: Haploid $(n)$$5$. Sperm: Haploid $(n)$$6$. Oogonia: Diploid $(2n)$$7$. Spermatogonia: Diploid $(2n)$$8$. Polar body: Haploid $(n)$The haploid structures are: Spermatid,secondary oocyte,ovum,sperm,and polar body.Counting these,we get a total of $5$ haploid structures.
