Solution
The correct option is BH+ The first chemical definition of an acid and a base was put forward by Svante Arrhenius.
He stated that an acid is a substance that releases H+ ions in an aqueous solution. H+ ions do not exist independently and they combine with water molecules to form H3O+ or hydronium ions.
He stated that a base is a substance that gives hydroxide or OH− ions in an aqueous solution.
