Explanation
Hyaluronidase enzyme is present in the acrosome of the sperm cell. The acrosome is an organelle in the head of the sperm that contains enzymes that help the sperm penetrate the egg during fertilization. Hyaluronidase is one of the enzymes present in the acrosome, and it helps the sperm to break down the hyaluronic acid in the extracellular matrix surrounding the egg. This allows the sperm to penetrate the protective barriers of the egg and fertilize it. Zona pellucida is the outermost layer of the mammalian ovum or egg, and follicle cells are cells that surround the developing egg in the ovary. The middle piece of the sperm contains the mitochondria, which provides the energy for the sperm to move. Therefore, the correct answer is B: Acrosome.
