Explanation:

An aqueous solution is a solution in which water is the solvent. The notation (aq) indicates that the substance is dissolved in water. \( \text{H}_2\text{O}(\text{l}) \) is liquid water, not a solution. \( \text{AgCl}(\text{s}) \) and \( \text{SrCO}_3(\text{s}) \) are solids, not solutions. \( \text{C}_2\text{H}_6\text{O}(\text{l}) \) is liquid ethanol, not an aqueous solution. \( \text{Co(NO}_3\text{)}_2(\text{aq}) \) and \( \text{NaBr}(\text{aq}) \) have the (aq) notation, meaning they are dissolved in water (aqueous solutions).

Answer:

B. \( \text{Co(NO}_3\text{)}_2(\text{aq}) \), C. \( \text{NaBr}(\text{aq}) \)
