The correct option is A Distal centriole
The male gamete or sperm has 4 parts- head, neck, body and tail. The head contains the nucleus and the acrosome. The neck contains centrioles i.e., distal centriole and the proximal centriole. The function of the distal centriole is to form the axial filament. The centrioles help in cell division after fertilization. Mitochondria provides energy for movement of the sperm. So the correct answer is A.
