The correct option is D yeast
Statins are products of fermentation by the yeast Monascus purpureus. Statins resemble mevalonate and are competitive inhibitors of HMG (β-hydroxy-β- methylglutaryl) CoA reductase, an enzyme in the cholesterol biosynthesis pathway. Statins are, therefore, used in lowering blood cholesterol, e.g., lovastatin, pravastatin, simvastatin.
