When assessing a patient's plan for suicide, what aspect has priority?

A. Social support is important for overall risk formulation and safety planning, but it is not the immediate priority when assessing imminent danger. B. Financial and educational status may contribute to chronic stress and long-term risk, but they do not determine immediate lethality or imminence. C. The availability of means and the lethality of the chosen method are the most urgent factors to assess because they directly influence the likelihood that an attempt will result in death. Removing or restricting access to lethal means is a high-priority, evidence-based safety intervention. D. Insight into motivation helps guide treatment and psychotherapy, but it does not supersede immediate safety concerns about access to lethal methods.
