In which of the following , cellulose content is maximum?

Options

A. Cotton fibres
B. Wood
C. Rayon
D. Silk

Answer

To determine which of the given options has the maximum cellulose content, we need to analyze each option based on their cellulose composition:

1. **Cotton Fibers**:
- Cotton fibers are known for their high cellulose content. In fact, cotton is composed of approximately 90% cellulose. This makes it one of the purest forms of cellulose found in nature.

2. **Wood**:
- Wood contains cellulose as well, but its content is lower than that of cotton. The cellulose content in wood typically ranges from 40% to 50%. Therefore, while wood does contain cellulose, it is not as concentrated as in cotton.

3. **Rayon**:
- Rayon is a synthetic fiber made from cellulose. However, it is important to note that rayon is a processed form of cellulose and does not contain cellulose in its original form. Thus, it cannot be compared directly to the other options in terms of cellulose content.

4. **Silk**:
- Silk is a protein fiber and does not contain cellulose at all. Therefore, it has 0% cellulose content.

After analyzing all the options, we can conclude that:

- Cotton fibers have the highest cellulose content at approximately 90%.
- Wood has a cellulose content of 40-50%.
- Rayon is derived from cellulose but does not contain it in its original form.
- Silk has no cellulose content.

Thus, the correct answer is **cotton fibers**.

### Final Answer:
Cotton fibers have the maximum cellulose content.
