Final answer:
Social Security provides retirement income, survivor's benefits, and disability income but does not directly offer unemployment income, which is a separate program managed through unemployment insurance. The correct option is A.
Step-by-step explanation:
Social Security was created to provide a variety of benefits to Americans, particularly as they age or if they encounter certain life events that impact their income-earning ability. The Social Security program includes benefits such as retirement income, survivor's benefits, and disability income. These are provided based on the contributions workers make through payroll taxes over their working lives.
However, one of the benefits Social Security does not provide directly is unemployment income. Unemployment insurance is a separate program that is also financed through taxes on employers and employees, and it provides financial compensation to workers who have been laid off or are temporarily out of work.
Hence, the correct answer to the student's question is 'a) Unemployment income.'
