Which of the following is an example of a conductor?

Only the salt solution is a conductor among the possibilities.

Sodium ions make up the salt solution. ${\mathrm{Na}}^{+}$and chlorine ${\mathrm{Cl}}^{-}$ions.

The transport of ions to the electrodes' opposing ends permits electric current to pass through the salt solution.

Only charged particles (electrons/ions) that are free to move about in a material may conduct electricity.

Silver is the best conductor of electricity.

Insulators are materials that do not readily conduct electricity and have high resistance.

Because sugar molecules are neutral (uncharged), they cannot migrate to the opposite ends of the electrodes like ions.

Insulators include plastic, PVC, glass, sugar solution, mica, rubber, and nylon.
