To determine which statements are correct, we need to evaluate each one based on what is known about autoimmune disorders and rheumatoid arthritis.
Statement I: "Autoimmune disorder is a condition where the body defense mechanism recognizes its own cells as foreign bodies." This statement is accurate. An autoimmune disorder occurs when the immune system mistakenly attacks the body's own cells, thinking they are foreign invaders.
Statement II: "Rheumatoid arthritis is a condition where the body does not attack self cells." This statement is incorrect. Rheumatoid arthritis is indeed an autoimmune disorder, where the immune system attacks the joints as if they were foreign tissues, leading to inflammation and pain.
Based on the evaluation, Statement I is correct but Statement II is incorrect.
