Answer:
Correct Answer: Mood disorder
Step-by-step explanation:
Biopolar disorder is a mental health disorder whereby the person has an extreem mood swing over a given period of time. For example, someone that was laughing over a joke 5 minutes ago becoming extreemly angry and agitated without an external influence. It is also known as manic depression.
On the otherhand, depression is a state of feeling sad due to a rough situation or event in your life. Dwelling in that state is very bad for the mental health of the person.
