The correct Answer is:
**Step-by-Step Solution:** 1. **Identify the Material**: The question asks for the material used to make polythene bags. The term "polythene" itself is a clue. 2. **Define Polythene**: Polythene, also known as polyethylene, is a type of polymer. Polymers are large molecules made up of repeating units called monomers. 3. **Identify the Monomer**: The monomer that makes up polythene is ethylene. The chemical structure of ethylene is represented as CH2=CH2, indicating that it has a double bond between two carbon atoms. 4. **Polymerization Process**: When ethylene undergoes a chemical reaction called polymerization, it forms long chains of repeating units, resulting in polythene. This process involves breaking the double bond in ethylene and linking the monomers together. 5. **Conclusion**: Therefore, the answer to the question is that "polythene" is used for making polythene bags. **Final Answer**: Polythene is used for making polythene bags. ---
