Which of the following compounds acts as an inhibitor of HMG-CoA reductase?

Explanation

HMG-CoA reductase is the enzyme targeted by statins such as Lovastatin, which reduce cholesterol synthesis. Clofibrate and Gemfibrozil are fibrates that primarily affect triglyceride levels, while Cholestyramine is a bile acid sequestrant that lowers cholesterol by binding bile acids in the intestine.
