Answer: Option (2) is the correct answer.

Explanation:

Arrhenius acid are the species that donate a H^{+} ion or proton.

For example, HBr \rightarrow H^{+} + Br^{-}

Whereas LiF, Mg(OH)_{2}, and CH_{3}CHO are the substances which do not give a proton upon dissociation. Hence, they are not Arrhenius acids.

Therefore, we can conclude that HBr(aq) substance is an Arrhenius acid.
