Takahashi and Kohda (2004) Found That Female Gobies (Rhinogobius Brunneus)

Takahashi and Kohda (2004) found that female gobies (Rhinogobius brunneus) preferentially choose to mate with males that perform their courtship dance in the fastest water currents. This seems to be related to the fact that males who are unable to court in fast moving water are

A) carrying too heavy a parasite load to be producing healthy sperm.
B) more likely to consume their own eggs during a two week guarding period.
C) not able to successfully defend a territory of sufficient quality to support a viable brood of fry.
D) too weak to keep up with the female's egg production schedule.
