Aqueous solution of which of the following compounds is the best conductor of electric current?

Conductance in aqueous solution depends on the concentration of ions.${\text{NH}}_3$ is a weak base, partially ionized.Fructose is a non-electrolyte, it does not ionize.Acetic acid is a weak acid, partially ionized.$\text{HCl}$ is a strong acid and dissociates completely into ${\text{H}}^{+}$ and ${\text{Cl}}^{-}$ ions, providing the highest concentration of charge carriers.
