Final answer:
General wear and tear on joints may result in 2) osteoarthritis.
Step-by-step explanation:
General wear and tear on joints may result in osteoarthritis, which is a joint disorder that occurs from the breakdown of joint cartilage and bone, most commonly due to the process of aging or the prolonged wear and tear on joints. It is characterized by symptoms such as joint pain and stiffness, which can lead to decreased movement and, over time, a loss of function in the affected areas. Commonly affected joints include those in the hands, spine, hips, and knees.
Unlike some other forms of arthritis, osteoarthritis is directly related to the mechanical stress on the joints coupled with insufficient self-repair of cartilage. The affected cartilage becomes thinner as it wears down, contributing to the onset of symptoms. As the disorder progresses, it can lead to severe joint pain and immobility and while there is no cure, treatments like lifestyle changes, medication, and sometimes surgery for severe cases are available to manage osteoarthritis and improve quality of life. Thus, the correct answer to the student's question is option 2: osteoarthritis.
