Kerosene oil is an example of

Options

A. conductor
B. insulator
C. Electrolyte
D. none of these.

Explanation

**Step-by-step Solution:**

1. **Understanding the Options**: The question provides four options: Conductor, Insulator, Electrolyte, and None of these. We need to determine which category kerosene oil falls into.

2. **Defining Conductors**: Conductors are materials that allow electric current to pass through them easily. Examples include metals like copper and aluminum.

3. **Defining Insulators**: Insulators are materials that do not allow electric current to flow through them. They resist the flow of electric current. Common examples include rubber, glass, and kerosene oil.

4. **Defining Electrolytes**: Electrolytes are substances that produce an electrically conducting solution when dissolved in a solvent. They are typically ionic compounds. Examples include saltwater and acids.

5. **Analyzing Kerosene Oil**: Kerosene oil is a hydrocarbon and does not contain free ions that can carry electric current. Therefore, it does not conduct electricity.

6. **Conclusion**: Since kerosene oil does not allow electric current to flow through it, it is classified as an insulator.

7. **Final Answer**: Kerosene oil is an example of an insulator.
