Answer:
B
Explanation:
A zygote is the resulting cell from fertilization.
Fertilization occurs when the sperm (the male gamete/sex cell) fuses with the egg (the female gamete/sex cell). After they fuse, or fertilize, a cell forms that contains half of the DNA from the father (sperm) and the other half from the mother (egg). It has a complete set of DNA, and is considered a haploid cell.
It is not the structure that nourishes the fetus, an un-fertilized egg, or a ball of about 100 cells. Therefore, the correct answer is <u>B: a sperm fused with an egg.</u>
