The correct option is D.
Behavioral isolation refers to the isolation that occur as a result of reproductive barriers based on behavior. The signals that attract sexual mates to one another is one of the most important determinant factors that determine whether closely related species will be able to mate successfully or not. Behavioral isolation is a type of speciation, which occur when similar species that live in the same environment are unable to mate as a result of differences in sexual behaviors. The sexual behaviors are usually in the form of mating rituals and signals.

The correct answer is option D, that is, behavioral isolation.  

Both the Blue rays and Cardinals were developed by the process of behavioral isolation. Behavioral isolation refers to the separation that takes place as a consequence of reproductive barriers on the basis of behavior. Even though they hold a similar zone of habitat at a similar time of the year, their courtship differences (behavioral isolation) signifies that they do not mate with one another.
