Answer:The correct answer is option 4.

Step-by-step explanation:

Arrhenius acids are those compounds which gives
H^+ ions when dissolved in their aqueous solution.

$HA(aq)\rightarrow H^++A^-$

Arrhenius bases are those compounds which gives
OH^- ions when dissolved in their aqueous solution.

$BOH(aq)\rightarrow OH^-+B^+$

$HBr \& H_2SO_4$ are Arrhenius acids because they form
ions in their respective aqueous solution.

$HBr(aq)\rightarrow H^++Br^-$

$H_2SO_4(aq)\rightarrow 2H^++SO_(4)^(2-)$

Hence, the correct answer is option 4.
