It is important to note that any warning sign of depression can potentially lead to suicide, and it is crucial to take any sign seriously. However, if we must choose an option that is typically less strongly associated with suicide risk, it would be option C: "Sudden weight loss or gain."

Nonetheless, it is vital to consider the overall context and seek professional help if any signs of depression are present.
