The correct option is D None of the above
Gout is a clinical condition. Gout is a kind of arthritis. It can cause an attack of sudden burning pain, stiffness and swelling in a joint, usually a big toe. These attacks can happen over and over unless gout is treated. Over time, they can harm your joints, tendons and other tissues. Gout is most common in men. Gout is caused by too much uric acid in the blood. Most of the time, having too much uric acid isn't harmful. Many people with high levels in their blood never get gout. But when uric acid levels in your blood are too high, the uric acid may form hard crystals in your joints. It's not a degenerative disease, infectious disease and deficiency disease. Thus, option D is correct.
