The substances such as HCl, HNO₃, etc. are Arrhenius acids whereas the substances like NaOH, KOH, etc. are Arrhenius bases. An Arrhenius acid donates H⁺ ions. The correct option is B.
According to Arrhenius, an acid is defined as a substance which dissociates to give hydrogen ions in aqueous solution and base is a substance which dissociates to give hydroxyl ions in aqueous solution.
So the Arrhenius acid ionize in water to give H⁺ ions and Arrhenius base ionize in water to form OH⁻ ions.
Thus Arrhenius acid is option B.
