Which of the following does not describe a function of aggressive animal behavior? a. aggressive behavior leads to fights that allow strong animals kill off weaker members of the species. b. aggressive behavior is displayed to establish territorial boundaries. c. aggressive behavior is displayed to establish hierarchy without violence. d. aggressive behavior is displayed to determine who is allowed to mate.

Statement C doesn’t describe about the function of aggressive animal behavior.

Instead of aggressive behavior, dominance is used to form hierarchy with non-violence. It is a sort of social pecking order that emerges when animals from a social gathering collaborate, to make a positioning framework.  

In social living gatherings, they are probably going to vie for access to constrained assets and mating openings. Instead of battling each time they meet, the relative position is set up between individuals from similar sex.

Thus, in order to establish hierarchy without violence, dominance is used.

looks like the answer is     c     to me!
