Question

Assertion (A): Scleroderma is a systemic autoimmune disease. Reason (R): In Scleroderma, immune response is directed toward nuclei, heart, lungs, kidney and gastrointestinal tract.

• A. Both (A) and (R) are correct and (R) is the correct explanation of (A).
• B. Both (A) and (R) are correct but (R) is NOT the correct explanation of (A).
• C. (A) is correct but (R) is not correct.
• D. (A) is not correct but (R) is correct.

Hint:

Systemic = The whole system. If it attacks the heart, lungs, and kidneys, it's systemic!

Answer 1

The Correct Option is A

Step 1: Concept
Autoimmune diseases occur when the immune system attacks the body's own tissues.

Step 2: Meaning
“Systemic” means it affects multiple organs throughout the body.

Step 3: Analysis
Assertion (A) correctly identifies Scleroderma as systemic. Reason (R) lists the various internal organs targeted. Because it attacks all these different systems, it is classified as systemic.

Step 4: Conclusion
(R) is the direct evidence and explanation for why the disease is called “systemic” (A).

Final Answer: (A)
