Final Answer :
C
Explanation :
Studies have shown that abnormalities on the serotonin transporter gene could affect the stability of individuals' moods. This suggests that genetic factors play a role in the development of depression. However, it is important to note that genetics is not the only factor that contributes to depression, as environmental factors also play a significant role.
