Question

Assertion (A): An organ transplant patient, if not provided with cyclosporin A, may reject the transplanted organ.

Reason (R): Cyclosporin A inhibits activation of T-cells and interferes with destruction of non-self cells.

Options

• Both assertion (A) and reason (R) are true, and reason is the correct explanation of assertion.

• Both assertion (A) and reason (R) are true, but reason is not the correct explanation of assertion.

• Assertion (A) is true but reason (R) is false.

• Both assertion (A) and reason (R) are false.

Answer 1

Both assertion (A) and reason (R) are true, and reason is the correct explanation of assertion.

Explanation:

Both statements are true. Cyclosporin A suppresses T-cell activation and the immune attack on a transplanted organ, so without immunosuppression the organ may be rejected.
