(D) Bronsted acid is a proton $(H^{+})$ donor,and a Bronsted base is a proton $(H^{+})$ acceptor. Amphoteric species can act as both.$1$. $HCl$: Only acts as an acid $(HCl \rightarrow H^{+} + Cl^{-})$.$2$. $ClO_4^{-}$: Only acts as a base $(ClO_4^{-} + H^{+} \rightarrow HClO_4)$.$3$. $OH^{-}$: Only acts as a base $(OH^{-} + H^{+} \rightarrow H_2O)$.$4$. $H^{+}$: Only acts as an acid.$5$. $H_2O$: Acts as an acid $(H_2O \rightarrow H^{+} + OH^{-})$ and as a base $(H_2O + H^{+} \rightarrow H_3O^{+})$.$6$. $HSO_4^{-}$: Acts as an acid $(HSO_4^{-} \rightarrow H^{+} + SO_4^{2-})$ and as a base $(HSO_4^{-} + H^{+} \rightarrow H_2SO_4)$.$7$. $SO_4^{2-}$: Only acts as a base $(SO_4^{2-} + H^{+} \rightarrow HSO_4^{-})$.$8$. $H_2SO_4$: Only acts as an acid $(H_2SO_4 \rightarrow H^{+} + HSO_4^{-})$.$9$. $Cl^{-}$: Only acts as a base $(Cl^{-} + H^{+} \rightarrow HCl)$.Thus,only $H_2O$ and $HSO_4^{-}$ can act as both Bronsted acids and bases. The total number is $2$.

The number of species among the following that can act both as Bronsted acids and bases is $HCl, ClO_4^{-}, OH^{-}, H^{+}, H_2O, HSO_4^{-}, SO_4^{2-}, H_2SO_4, Cl^{-}$.
