Quizplus · Accepted Answer

Dynein feet are responsible for the movement and swimming of sperm cells. If they are missing from the flagella, the sperm cells will not be able to effectively swim to the egg cell, which can interfere with fertility. A and B are incorrect because the dynein feet are not involved in attaching to the egg or the flagella. C is incorrect because while dynein feet are involved in energy production, their absence does not necessarily mean the sperm cannot produce enough energy to swim at all.
