The correct Answer is:
**Step-by-Step Solution:** 1. **Identify the Subject Matter**: The question asks about statins and their role as competitive inhibitors. Statins are a class of drugs primarily used to lower cholesterol levels in the blood. 2. **Understand the Function of Statins**: Statins work by inhibiting a specific enzyme involved in cholesterol biosynthesis, which helps in reducing plasma cholesterol levels and, consequently, the risk of cardiovascular diseases. 3. **Identify the Enzyme Targeted by Statins**: The key enzyme that statins inhibit is HMG-CoA reductase. This enzyme is crucial in the cholesterol synthesis pathway and is considered the rate-limiting step in this process. 4. **Evaluate the Options Provided**: The question provides four options: - A. Streptokinase - B. HMG-CoA reductase - C. Pectinase - D. Cellulase 5. **Select the Correct Answer**: Since statins are known to be competitive inhibitors of HMG-CoA reductase, the correct answer from the options provided is B. HMG-CoA reductase. 6. **Conclusion**: Therefore, the answer to the question is that statins are competitive inhibitors of HMG-CoA reductase. ---
