Best answer
The correct option is (b) It occurs only in old people

The explanation is: Rheumatoid arthritis is an autoimmune disorder that can occur at any age. The primary symptom is inflammation of the synovial membrane. If it is left untreated, then the membrane thickens and synovial fluid increases, exerting pressure that causes pain.
