The polymer used in the manufacture of squeeze bottles is:

Options

A. Polystyrene
B. Teflon
C. Polypropylene
D. low density polythene

Explanation

To solve the question regarding the polymer used in the manufacture of squeeze bottles, we will analyze the given options one by one.

### Step-by-Step Solution:

1. **Identify the Polymers**: The question provides four polymers as options. We need to evaluate each one to see which is used for squeeze bottles.

2. **Evaluate Polystyrene**:
- Polystyrene is primarily used as an insulator and in wrapping materials.
- **Conclusion**: Polystyrene is not used for squeeze bottles.

3. **Evaluate Polypropylene**:
- Polypropylene is commonly used in the manufacturing of carpet fibers, ropes, toys, and pipes.
- **Conclusion**: Polypropylene is not used for squeeze bottles.

4. **Evaluate Teflon (PTFE)**:
- Teflon, known as PTFE, is mainly used for making gaskets and nonstick utensils.
- **Conclusion**: Teflon is not used for squeeze bottles.

5. **Evaluate Low-Density Polyethylene (LDPE)**:
- Low-density polyethylene is known for its flexibility and is widely used in the manufacture of squeeze bottles, flexible pipes, and packaging materials.
- **Conclusion**: LDPE is indeed used for squeeze bottles.

6. **Final Answer**: Based on the evaluations, the polymer used in the manufacture of squeeze bottles is **Low-Density Polyethylene (LDPE)**.
