Cirrhosis of liver is caused due to the intake of

Options

A. Cocaine
B. Opium
C. Alcohol
D. Tobacco

Answer

### Step-by-Step Solution:

1. **Understanding Cirrhosis of the Liver**:
- Cirrhosis is a progressive disease where the liver becomes severely scarred due to long-term damage. This scarring impairs the liver's ability to function properly.

2. **Identifying Causes**:
- The primary cause of cirrhosis is the continued intake of harmful substances, particularly alcohol. Other potential causes can include viral hepatitis and fatty liver disease, but for this question, we focus on alcohol.

3. **Mechanism of Damage**:
- When alcohol is consumed regularly, it leads to the destruction of liver cells (hepatocytes) and stimulates the formation of collagen, which causes fibrosis (scarring) in the liver. This process disrupts the normal structure and function of the liver.

4. **Evaluating Options**:
- The question provides multiple options: cocaine, opium, alcohol, and tobacco.
- Cocaine and opium are not directly linked to causing cirrhosis. Tobacco can contribute to various health issues but is not a primary cause of liver cirrhosis.

5. **Conclusion**:
- Based on the understanding that continued alcohol intake leads to liver damage and cirrhosis, the correct answer is **alcohol**.

### Final Answer:
Cirrhosis of the liver is caused due to the intake of **alcohol**.
