Vedclass · Answer

(A) An amphoteric substance is one that can act as both an acid and a base.$HCO_3^-$ can accept a proton to form $H_2CO_3$ or donate a proton to form $CO_3^{2-}$.$H_2O$ can accept a proton to form $H_3O^+$ or donate a proton to form $OH^-$.$NH_3$ can accept a proton to form $NH_4^+$ or donate a proton to form $NH_2^-$.$HNO_3$ is a strong acid and acts only as a proton donor; it does not exhibit amphoteric behavior.Therefore,the correct option is $A$.
