Final Answer :
B
Explanation :
The sex of the zygote is determined by the sex chromosomes carried by the sperm. Sperm contain either an X chromosome or a Y chromosome, while egg cells always carry an X chromosome. When a sperm carrying an X chromosome fertilizes an egg, the resulting zygote will have XX chromosomes and develop into a female. When a sperm carrying a Y chromosome fertilizes an egg, the resulting zygote will have XY chromosomes and develop into a male. Therefore, the correct choice is B) sperm.
