​According to the APA (DSM-5, 2013), Bipolar Disorder Involves Both

​According to the APA (DSM-5, 2013) , bipolar disorder involves both depressive and manic (and/or hypomanic) symptoms; as such, it is neither precisely a depressive disorder nor an anxiety disorder (the DSM classifies it under "Bipolar and Related Disorders") . However, extrapolating from the research literature on depression and anxiety, what would be the most reasonable inference to draw about a relationship between bipolar disorders and stress?

A) ​There is likely no relationship since bipolar disorder is different from depressive or anxiety disorders.
B) ​There is likely some relationship since at least one bipolar component, depression, is related to stress.
C) ​There is likely no relationship since no research has connected manic/hypomanic states with stress.
D) ​There is likely some relationship since manic and hypomanic states are equivalent with anxiety states.
