C. Assertion is true but Reason is false
D. Assertion is false but Reason is true

Explanation

### Step-by-Step Solution

1. **Understanding the Assertion**: The assertion states that "Excess consumption of alcohol results in damage to the liver." This is a well-established fact in medical science. Excessive alcohol intake can lead to various liver diseases, including fatty liver disease, alcoholic hepatitis, and cirrhosis.

**Hint**: Consider the effects of alcohol on the liver and the diseases associated with excessive consumption.

2. **Understanding the Reason**: The reason given is that "It promotes formation of fatty tissue in the liver." This is also true. When alcohol is consumed in excess, it can lead to the accumulation of fat in liver cells, a condition known as fatty liver disease.

**Hint**: Think about how alcohol metabolism affects liver cells and the process that leads to fat accumulation.

3. **Connecting Assertion and Reason**: The assertion and reason are linked. The formation of fatty tissue in the liver due to excessive alcohol consumption is a direct cause of liver damage. Fatty liver can progress to more severe liver conditions if not addressed.

**Hint**: Reflect on how the reason explains the mechanism behind the assertion.

4. **Conclusion**: Both the assertion and the reason are true, and the reason correctly explains the assertion. Therefore, the answer to the question is that both the assertion and reason are true, and the reason is a correct explanation of the assertion.

**Hint**: Summarize the relationship between the assertion and reason to confirm their validity.

### Final Answer
Both the assertion and the reason are true, and the reason is a correct explanation of the assertion.
