The solution of a substance which conducts electricity is called ………………

Options

A. an electrolyte
B. a conductor
C. an insulator
D. None of these

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question is asking for the term that describes a solution of a substance that is capable of conducting electricity.

2. **Defining the Key Term**: The term that fits this description is "electrolyte." An electrolyte is a substance that, when dissolved in water (or another solvent), dissociates into ions.

3. **Explaining Ion Dissociation**: When an electrolyte dissolves in water, it breaks apart into positively charged ions (cations) and negatively charged ions (anions). This dissociation is crucial because the movement of these ions in the solution allows it to conduct electricity.

4. **Differentiating from Other Terms**:
- A "conductor" is a material that can conduct electricity but is not specifically a solution. It refers to solids or materials that allow the flow of electric current.
- An "insulator" is a material that does not conduct electricity at all.

5. **Conclusion**: Therefore, the correct answer to the question is that the solution of a substance which conducts electricity is called an "electrolyte."

**Final Answer**: The solution of a substance which conducts electricity is called an **electrolyte**.
