Carl's aggressive behavior could be due to genetic inheritance,exposure to violent media,or living in a violent neighborhood.This reflects the developmental principle of:

A) psychopathology.
B) comorbidity.
C) multifinality.
D) equifinality.

The developmental principle of equifinality suggests that there are multiple pathways or factors that can lead to a particular outcome. In this case, Carl's aggressive behavior may be influenced by genetic inheritance, exposure to violent media, or living in a violent neighborhood, all of which are different contributing factors that could lead to the same outcome. Therefore, the best choice is D - equifinality.
