Answer:The correct answer is option 4.
Explanation:
Arrhenius acids are those compounds which gives [tex]H^+[/tex] ions when dissolved in their aqueous solution.
[tex]HA(aq)\rightarrow H^++A^-[/tex]
Arrhenius bases are those compounds which gives [tex]OH^-[/tex] ions when dissolved in their aqueous solution.
[tex]BOH(aq)\rightarrow OH^-+B^+[/tex]
[tex]HBr \& H_2SO_4[/tex] are Arrhenius acids because they form [tex]H^+[/tex]ions in their respective aqueous solution.
[tex]HBr(aq)\rightarrow H^++Br^-[/tex]
[tex]H_2SO_4(aq)\rightarrow 2H^++SO_{4}^{2-}[/tex]
Hence, the correct answer is option 4.
