Answer 1

The correct option is C Rheumatic arthritis

Rheumatoid arthritis is a consequence of changes in the body's immune system which attacks the soft tissue of the joints causing inflammation, swelling and pain. It worsens at old age causing severe pain and incapability to move joints.
Sprain is a stretch or tear of a ligament while a strain is an injury to a muscle or tendon.
Osteoporosis is a disease in which the density and the quality of the newly formed bone is reduced. This thinning of bone can cause painful fracture.
