Which of the following is naturally occurring polymer?

Options

A. Polythene
B. Starch
C. Nylon
D. Teflon

Answer

To determine which of the following is a naturally occurring polymer, we need to analyze the options provided and understand the definition of naturally occurring polymers.

### Step-by-Step Solution:

1. **Understand the Definition of Naturally Occurring Polymers**:
- Naturally occurring polymers are those that are found in nature and are not synthesized artificially. They are obtained from natural resources.

2. **Identify the Options**:
- The question implies that there are multiple choices, but we will focus on common examples of polymers to analyze.

3. **Evaluate Each Option**:
- **Polyethylene**: This is a synthetic polymer made from the polymerization of ethylene (CH2=CH2). Therefore, it is not a naturally occurring polymer.
- **Nylon**: This is also a synthetic polymer that is created through chemical processes. It is not found in nature.
- **Teflon**: Similar to nylon and polyethylene, Teflon is synthesized from tetrafluoroethylene and is not a naturally occurring polymer.
- **Starch**: Starch is a naturally occurring polymer made up of glucose units. It is found in many plants and is used as an energy storage molecule.

4. **Conclusion**:
- Among the options, starch is the only naturally occurring polymer, as it is derived from natural sources like plants.

### Final Answer:
- The naturally occurring polymer is **Starch**.
