Roxy's mother complains of pain and stiffness in her knees, and she says, "it's just something that happens when you get older." roxy wants to avoid this as long as she can. what can she do to decrease the chance future knee problems?

Through my research I found matching questions with options:

A. Stop exercising
B. Exercise regularly
C. Run for exercise only
D. Sleep with knees elevated

Among those choices the answer would be B) because exercising helps relieve pain physically and emotionally so not exercising wont help at all, sleeping with knees elevated wont help, and running wont help at all, in order to help you have to exercise in many ways to cure your knees.
