Answer:
The correct answer is option A.
Explanation:
According to the Arrhenius concept:
Acid are defined as those substance which gives hydrogen ions in their aqueous solution when dissolved in water.
[tex]HA(aq)\rightarrow H^+(aq)+A^-(aq)[/tex]
Base are defined as those substance which gives hydroxide ions in their aqueous solution when dissolved in water.
[tex]BOH(aq)\rightarrow B^+(aq)+OH^-(aq)[/tex]
So, when NaOH were dissolved in water, it would act as a base as it will give hydroxide ion in its aqueous solution.
[tex]NaOH(aq)\rightarrow Na^+(aq)+OH^-(aq)[/tex]
