What is the BEST conductor of electricity?
AI Explanation
The correct answer is D) Salt water.
Salt water is the best conductor of electricity among the options provided. This is because salt water contains dissolved ions, such as sodium and chloride, which can freely move and carry electric current. The presence of these charged particles in salt water makes it a better conductor compared to distilled water, fresh water, or carbon dioxide, which are poor conductors of electricity.
The other options are incorrect because distilled water and fresh water have very low ion concentrations, making them poor conductors, while carbon dioxide is a gas and does not contain the necessary charged particles to effectively conduct electricity.
