Options

A. Acrylic
B. Nylon
C. Polyester
D. Rayon

Explanation

**Step-by-Step Solution:**

1. **Identify the Fabrics**: The question asks about Dacron and Terylene. Both of these are types of synthetic fabrics.

2. **Understand the Composition**: Dacron and Terylene are made from the same type of polymer. They are both forms of polyester.

3. **Define Polyester**: Polyester is a category of polymers that contain the ester functional group in their main chain.

4. **Monomeric Units**: The monomers used to create Dacron and Terylene are ethylene glycol and terephthalic acid.

5. **Polymerization Process**: The process involves the condensation of these monomers, where water is removed to form long chains of polyester.

6. **Conclusion**: Therefore, Dacron and Terylene are types of polyester.

**Final Answer**: Dacron and Terylene are types of polyester.
