Boric acid is a weak Lewis acid. When it is dissolved in water, the aqueous solution contains ions :
(A) \( \mathrm{H}_{3} \mathrm{BO}_{3} \rightleftharpoons \mathrm{H}_{2} \mathrm{BO}_{3}^{-}+\mathrm{H}^{+} \)
(B) \( \mathrm{H}_{3} \mathrm{BO}_{3}+\mathrm{H}_{2} \mathrm{O} \rightleftharpoons \mathrm{B}(\mathrm{OH})_{4}^{-}+\mathrm{H}^{+} \)
(C) \( \mathrm{H}_{3} \mathrm{BO}_{3} \rightleftharpoons \mathrm{HBO}_{3}^{2-}+2 \mathrm{H}^{+} \)
(D) \( \mathrm{H}_{3} \mathrm{BO}_{3} \rightleftharpoons \mathrm{BO}_{3}^{3-}+3 \mathrm{H}^{+} \)
