Rationale: A. Family conflict can increase stress and contribute to suicidal thoughts but is not the greatest single risk factor. B. Availability of firearms increases the lethality of suicide attempts but is not the greatest underlying risk factor. C. Homosexuality itself is not a risk factor; however, lack of support, stigma, or bullying may increase risk. D. An active psychiatric disorder, such as depression or bipolar disorder, is the greatest risk factor for suicide in adolescents.
