Best answer

Answer: 4. Statement I is correct but Statement II is incorrect

Key idea: In autoimmunity the body attacks its own cells; rheumatoid arthritis is a typical example.

  • Statement I: an autoimmune disorder is where the defence mechanism wrongly treats self cells as foreign. Correct.
  • Statement II: rheumatoid arthritis is an autoimmune disease where the body does attack self cells (joint tissue). So the statement is incorrect.
