Answer:
D. the nature-nurture question.
Step-by-step explanation:
The "nature-nurture question" tackles on the behavior of humans as being inborn or acquired. This has always been a common debate since the 16th century. Some people say they were born like that because of their genes while other say they've been raised to be like that. Some recent discoveries relate genes to the person's behavior, which means people who are more genetically-related have more similar personalities and behavior.
