Solution

The correct option is B H+
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.
