Question

Given below are two statements:
Statement I: Autoimmune disorder is a condition where the body defense mechanism recognizes its own cells as foreign bodies.
Statement II: Rheumatoid arthritis is a condition where the 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

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
The immune system normally distinguishes between self and non-self cells. Autoimmunity is a failure of this distinction.
Detailed Explanation:
- Statement I: This is the correct definition of an autoimmune disorder. The body's immune system mistakenly attacks its own healthy tissues and cells.
- Statement II: Incorrect. Rheumatoid arthritis is a classic example of an autoimmune disease where the immune system does attack the self cells (specifically the synovial membrane of joints).
Step 2: Final Answer:
Statement I is true, but Statement II is false.
