Solution

The correct option is A

H+


According to Arrhenius, an acid is a substance that dissociates in water to form hydrogen ions (H+) and base is a substance that dissociates in water to form hydroxide (OH) ions.

For example: Hydrochloric acid (HCl) is an acid as it gives H+ in an aqueous solution and sodium hydroxide (NaOH) is a base as it dissociates in water to give OH ions.
