Which of the following is a natural polymer?

Options

A. Polythene
B. Polysaccharides
C. Nylon
D. Terylene

Answer

To determine which of the following is a natural polymer, we need to analyze the options provided and identify their origins.

### Step-by-Step Solution:

1. **Understanding Natural vs. Synthetic Polymers**:
- Natural polymers are those that occur in nature and can be extracted from natural sources, such as plants and animals.
- Synthetic polymers are man-made and are typically produced through chemical processes.

2. **Identifying the Options**:
- The options given are:
1. Polythene
2. Polysaccharides
3. Nylon
4. Terylene

3. **Analyzing Each Option**:
- **Polythene**: This is a synthetic polymer made from the polymerization of ethylene. It is not a natural polymer.
- **Polysaccharides**: These are natural polymers made from monosaccharides (sugars). They occur in nature and can be extracted from plants and animals. Examples include starch and cellulose.
- **Nylon**: This is a synthetic polymer made from the polycondensation of caprolactam. It is not a natural polymer.
- **Terylene**: This is also a synthetic polymer made from the polymerization of ethylene glycol and terephthalic acid. It is not a natural polymer.

4. **Conclusion**:
- Among the options provided, **polysaccharides** are the only natural polymers. Therefore, the correct answer is **Polysaccharides**.

### Final Answer:
The natural polymer from the given options is **Polysaccharides**.
