What would you do in this situation????

Jane Brown married Jim four years ago. Two years ago Jim lost his job. After looking for work for several months, Jim left town to look for work, and Jane has not heard from him. Jim's brother told Jane that he had heard that Jim lived in Texas, but a friend said he heard that Jim had been killed in an automobile accident. Jane went back to school and completed a program as a medical technician. She returned to work this year, and she earned $35,000. She has asked you to prepare her tax return this year. She has asked you whether she should file as a single taxpayer, married person filing separately, or as a married person filing jointly. Because she has had a low income until recently, she has taken no legal steps to resolve her status. What should she do? Explain in one or two paragraphs and prepare her tax return for this year.
