Question

which strategy can a person use to cope with suicidal thoughts on his or her own?
developing a safety plan
isolating himself or herself from people
limiting friendships with people
reading a book when feeling isolated

Explanation:

Developing a safety plan is a proactive and helpful approach. It can include steps like listing supportive contacts, safe places to go, and coping strategies. Isolating oneself (option 2) and limiting friendships (option 3) are counter - productive as social support is important. Reading a book when feeling isolated (option 4) is a very limited and not a comprehensive coping method compared to a safety plan.

Answer:

developing a safety plan
