Answer 1

The correct answer is option 3, i.e. Hydrogen ions.

Acids and Bases exhibit their conducting property only if they are in aqueous solution in which they could completely ionize in water.
As per Arrhenius' concept, acids are those that produce the hydrogen ion (H+) when dissolved in water.
Bases produce the hydroxide ion(OH-) when dissolved in water
These ions, when in water, act as charge carriers and can hence conduct electricity.
The pH level is a measure of the number of Hydrogen ions in a solution.
The lower the solution or compound on the pH scale, the higher will be the concentration of hydrogen ions.
