What does darwin’s principle of antithesis suggest?
a. submissive displays are opposite in form to dominant displays.
b. dogs are innately antagonistic towards one another.
c. dogs are the opposite of wolves in most behaviors.
d. .

The correct option is A.
Darwin's principle of antithesis states that some states of mind lead to specific habitual behavior and when a directly opposite state of mind is induced there is a strong, involuntary tendency to perform movements which are directly opposite in nature. An example of this is showing of submission signals by another dog to a dominant dog.
