____________ is used in electrical fittings, handles of utensils and crockery are made of thermosetting plastics.

Options

A. Melamine
B. PVC
C. Polythene
D. Teflon

Explanation

**Step-by-Step Text Solution:**

1. **Identify the context of the question**: The question asks for a material that is used in electrical fittings and the handles of utensils and crockery, specifically mentioning that it is a thermosetting plastic.

2. **Understand the properties of thermosetting plastics**: Thermosetting plastics are known for their durability and heat resistance. They do not melt upon heating and are often used in applications where strength and heat resistance are required.

3. **Consider common thermosetting plastics**: Some common thermosetting plastics include melamine, epoxy, and phenolic resins.

4. **Evaluate the options**:
- Melamine: Known for its heat resistance and electrical insulation properties, making it suitable for electrical fittings and kitchenware.
- PVC: Primarily used for pipes and not typically for utensils.
- Polythene: A thermoplastic, not a thermosetting plastic.
- Teflon: Known for its non-stick properties, primarily used in cookware but not typically for electrical fittings.

5. **Conclude with the correct answer**: Based on the properties and applications discussed, the correct answer is **melamine**. It is used in electrical fittings and the handles of utensils and crockery due to its heat and electrical resistance.

**Final Answer**: Melamine
