Condition caused by pain and swelling in joints.

Condition caused by pain and swelling in joints.

• A. Osteoarthritis
• B. Skeletal muscles
• C. Muscles
• D. Arthritis

Answer: (D)

Pain and swelling in joints point to arthritis, which is inflammation of one or more joints. Arthritis is the general term for this condition, encompassing any joint inflammation that causes pain, swelling, and stiffness. Osteoarthritis is a specific type of arthritis, but the description given matches the broader term arthritis best. The other options refer to tissues rather than a joint condition—they describe muscles or skeletal muscles, which are the structures that move joints, not the inflammatory disease itself. So arthritis is the correct term.
