Which disease is characterized by inflammation of the joints?

• A. Rheumatoid Arthritis
• B. Hydrarthrits
• C. Achondroplasia
• D. Rickets

Answer: (A)

Joint inflammation is the clue here. Rheumatoid arthritis is the autoimmune form of inflammatory arthritis, meaning the body's immune system mistakenly attacks the lining of the joints (the synovium). This causes swelling, warmth, pain, and stiffness, often in multiple joints on both sides of the body, and if not treated can lead to joint damage over time. The other options aren’t primarily diseases of joint inflammation: hydrarthrosis refers to excess fluid in a joint (a sign or symptom rather than a disease); achondroplasia is a genetic condition affecting bone growth; and rickets is vitamin D deficiency causing bone softening. So rheumatoid arthritis best fits the description of a disease characterized by inflammation of the joints.
