What Is the Most Likely Reason the 1

What is the most likely reason the 1.5-mm body of Drosophila bifurca has sperm that are 6 cm long?

A) The female's vaginal cavity is very deep and has a convoluted pathway.
B) The male has no penis-just an opening-and the sperm must create its own connection from the male opening to the female vagina.
C) The egg of this species is highly resistant to penetration,and the longer sperm stores sufficient energy to burrow through the egg wall.
D) The sperm can fill the female's sperm storage area,thus blocking competing male sperm.
