Answer

To solve the question regarding the formula of chitin present in the fungal wall, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Composition of Chitin**:
- Chitin is a polysaccharide, which means it is made up of many sugar units linked together. It is primarily composed of N-acetylglucosamine, which is an amino sugar.

2. **Identify the Chemical Formula**:
- The chemical formula for chitin can be derived from its monomer, N-acetylglucosamine. The formula for N-acetylglucosamine is C8H15N1O6.

3. **Determine the General Formula**:
- Since chitin is a polymer made from repeating units of N-acetylglucosamine, its general formula can be represented as (C8H13O5N)n, where 'n' indicates the number of repeating units.

4. **Choose the Correct Option**:
- Based on the options provided in the question, you would look for the formula that corresponds to chitin. The correct answer is typically represented as C8H13O5N.

5. **Conclusion**:
- Therefore, the formula for chitin present in the fungal wall is C8H13O5N.
