    I believe its D ... because an egg cell is XX and a sperm cell is XY

    Well it can't be C because the DNA of female cells do not have any Y sex chromosomes. It also can't be E because of that same reason (the egg is made by the female, so it can only contain her genes). It can't be A because zygotes are diploid (because the egg and sperm, both haploid with 23 chromosomes, fuse together to double the amount of chromosomes), so a zygote would have to have 46 chromosomes, not 23 with 22 being autosomal and 1 being allosomal/sexual like the question states. And finally, it can't be B because somatic cells are also diploid and have 46 chromosomes. Another clue it can't be B is that the question states it has only a Y chromosome, which means the cell can't be diploid because a diploid cell has two allosomal chromosomes, either XX or XY.
