Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A: Boric acid is a weak acid.
Reason R: Boric acid is not able to release $\displaystyle \mathrm{H}^{+}$ion on its own. It receives $\displaystyle \mathrm{OH}^{-}$ion from water and releases $\displaystyle \mathrm{H}^{+}$ion.
In the light of the above statements, choose the most appropriate answer from the options given below.
