Given below are two statements :
Statement I : Autoimmune disorder is a condition where body defense mechanism recognizes its own cells as foreign bodies.
Statement II : Rheumatoid arthritis is a condition where body does not attack self cells.
In the light of the above statements, choose the most appropriate answer from the options given below :
- A
Both Statement I and Statement II are correct
- B
Both Statement I and Statement II are incorrect
- C
Statement I is correct but Statement II is incorrect
- D
Statement I is incorrect but Statement II is correct
Autoimmune disorders arise when the body's own defence mechanism fails to distinguish self from non-self and attacks the body's own cells, recognising them as foreign. Statement I is correct.
Rheumatoid arthritis is itself a classical example of an autoimmune disorder; the immune system attacks the synovial lining of the joints. So the claim in Statement II that the body does not attack self cells in rheumatoid arthritis is incorrect.
