Question

Which one of the following diseases is caused due to immunological disorder against an unknown antigen?

• A. Stroke
• B. Tuberculosis
• C. Rheumatic arthritis
• D. Multiple sclerosis

Answer 1

The correct option is C Rheumatic arthritis

• Rheumatic arthritis is an example of an autoimmune disease that affects the joints.
• The autoimmune diseases are generated due to the activity of the immune cells against the self-cells.
• The immune cells are not able to distinguish between the self and the non-self cells.
• There is no known antigen that can provoke the immune cells to show an immune response against the cells of the body.

Thus, the correct answer is option C.
