Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Statins are produced by the yeast Monascus purpureus. Reason (R): Statins act by competitively inhibiting the enzyme responsible for the synthesis of cholesterol. In the light of the above statements, choose the most appropriate answer from the options given below:

Options

  1. ABoth (A) and (R) are true and (R) is the correct explanation of (A).
  2. BBoth (A) and (R) are true but (R) is not the correct explanation of (A).
  3. C(A) is true but (R) is false.
  4. D(A) is false but (R) is true.

Correct answer

B. Both (A) and (R) are true but (R) is not the correct explanation of (A).

Step-by-step solution

Assertion (A) is a correct statement as statins are bioactive molecules produced by the yeast Monascus purpureus. Reason (R) is also a correct statement because statins are used as blood-cholesterol lowering agents and they act by competitively inhibiting the enzyme responsible for the synthesis of cholesterol. However, the mechanism of action of statins in the human body (Reason) does not explain why they are produced by the yeast (Assertion). Therefore, both (A) and (R) are true, but (R) is not the correct explan
