Choice A rationale:

Being extroverted is not a common risk factor associated with suicide and suicidal ideation. Extroverted individuals typically have strong social interactions and connections, which are often considered protective factors against suicide.

Choice B rationale:

Having strong family support is not a common risk factor for suicide. In fact, strong family support is generally considered a protective factor that can mitigate the risk of suicidal thoughts and behaviors. Close familial relationships can provide emotional support and a sense of belonging.

Choice C rationale:

Experiencing chronic physical illness is a common risk factor for suicide. Chronic physical illness can lead to prolonged suffering, decreased quality of life, and feelings of hopelessness, which are all associated with an increased risk of suicidal ideation.

Having a history of positive life events is not a common risk factor for suicide. Positive life events are more likely to act as protective factors against suicide, as they contribute to an individual's overall well-being and resilience.

Suffering from a substance use disorder is a common risk factor for suicide. Substance abuse can impair judgment, increase impulsivity, exacerbate emotional distress, and weaken the individual's ability to cope effectively, all of which contribute to an elevated risk of suicidal thoughts and behaviors.
