Why do ionic compounds conduct electricity in the molten state but not in the solid state?

Q: What is the correct answer for CBSE10?

The correct answer is B. In the solid state, ions in an ionic compound are held in fixed positions by strong electrostatic forces, preventing movement. In the molten state, these forces are overcome by heat, allowing the ions to move freely and conduct electricity.
