Sophia is a 98-year-old woman who still lives independently, has no major illnesses, and is able to take daily walks to the local grocery store. which of the following best describes sophia's functional age?

I believe Sophia followed a healthy diet and exercise program appropriate for her. Most people on her age would have experienced problems with their health. But she displayed full abilities by doing tasks on her own and being free of any sickness. She has been successful in sustaining her good health condition.
