Which of the following is a natural polymer?

Options

A. Cellulose
B. Buna-S
C. Rayon
D. Nylon 6, 6

Answer

To determine which of the following is a natural polymer, we can analyze each option provided.

1. **Identify the options**: The options given are cellulose, Muna-S, Rayon, and Nylon-66.

2. **Define natural polymers**: Natural polymers are those that are found in nature and are not synthesized or artificially created. They are typically derived from plants, animals, or microorganisms.

3. **Analyze each option**:
- **Cellulose**: This is a natural polymer found in the cell walls of plants. It is composed of glucose units and is not synthesized artificially. Therefore, it is a natural polymer.
- **Muna-S**: This is not a widely recognized polymer and appears to be an artificial or synthetic polymer.
- **Rayon**: Although rayon is derived from cellulose (which is a natural polymer), it is processed and synthesized into a fiber form. Thus, rayon is considered a semi-synthetic polymer, not a natural polymer.
- **Nylon-66**: This is a synthetic polymer made from the reaction of hexamethylenediamine and adipic acid. It is entirely artificial and does not occur in nature.

4. **Conclusion**: The only option that qualifies as a natural polymer is cellulose.

Final Answer: **Cellulose**
