The answer is (2). The question only ask the production of acid reacts with base. The acid has H+ ion and base has OH- ion. When they react, the production will always contain H2O.

Answer: Option (B) is the correct answer.

Explanation:

According to Arrhenius, acid are the substance that produce hydrogen ions when dissolved in a solution.

For example, [tex]HBr \rightarrow H^{+} + Br^{-}[/tex] shows that HBr is an Arrhenius acid.

Whereas Arrhenius bases are the substances that produce hydroxide ions when dissolved in a solution.

For example,  [tex]KOH \rightarrow K^{+} + OH^{-}[/tex] shows that KOH is an Arrhenius base.

Therefore, when an Arrhenius acid in an aqueous solution reacts with an Arrhenius base in an aqueous solution then following reaction occurs.

                  [tex]HBr + KOH \rightarrow KBr + H_{2}O[/tex]

Thus, we can conclude that out of the given options, KBr is the product.
