• A. Rheumatoid Arthritis
• B. Osteoarthritis
• C. Systemic Lupus Erythematosus
• D. Gout

Answer: (A)

The main idea is autoimmune inflammation of the joints. Rheumatoid arthritis is an autoimmune condition where the immune system attacks the synovial lining of joints, causing synovitis and inflammation of the surrounding tissues. This leads to swelling, pain, and often prolonged morning stiffness, and it typically affects multiple joints in a symmetrical pattern. This clear autoimmune joint inflammation distinguishes it from other conditions: osteoarthritis is a non-autoimmune degenerative wear-and-tear process; gout is a crystal-induced inflammatory arthritis from uric acid deposition; and while lupus can involve joints, it is a systemic autoimmune disease with a broader set of symptoms, not primarily defined by autoimmune attack on joint tissues.
