Assertion $A$ : Boric acid is a weak acid
Reason $R$ : Boric acid is not able to release $H ^{+}$ion on its own. It receives $OH ^{-}$ion from water and releases $H ^{+}$ion.
In the light of the above statements, choose the most appropriate answer from the options given below.
Assume Planck's constant $( h )=6.4 \times 10^{-34}\,Js$ Speed of light $( c )=3.0 \times 10^8\,m / s$ and Avogadro's constant $\left( N _{ A }\right)=6 \times 10^{23} / mol$
