None of the above

Detailed explanation-1: -An Arrhenius base is any substance that gives the OH-, or hydroxide, ion when it dissolves in water. Arrhenius acids include compounds such as HCl, HCN, and H2SO4 that ionize in water to give the H+ ion. Arrhenius bases include ionic compounds that contain the OH-ion, such as NaOH, KOH, and Ca(OH)2.
Detailed explanation-2: -A base is a substance that releases hydroxyl ions (OH-) when in solution.
Detailed explanation-3: -Bases are substances that react with and neutralise acids, producing water. When dissolved, bases release hydroxide ions, OH-(aq) into solution.
Detailed explanation-4: -An Arrhenius base is a substance that dissociates in water to form hydroxide (OH−) ions. That is, a base increases the concentration of OH− ions in an aqueous solution.
