The correct answer is silver nitrate solution that is AgNO_3(aq) .

Explanation:

To separate Br^- from $NO_{3}^-$ ions we will use silver nitrate solution. On addition of silver nitrate solution in a mixture of bromide and nitrate ions.

The silver ion will react with bromide ions to form silver bromide which will get precipitated out as yellow color solid from a mixture.

$AgNO_3(aq)+Br^-(aq)\rightarrow AgBr(s)+NO_{3}^-(aq)$

$AgNO_3(aq)+NO_{3}^-(aq)\rightarrow$ no reaction
