Should be "Standard solution", shouldn't it?
Explanation:
None of the other possible answers work.
"Normal" means unit gram equivalent mass of solute per litre of solution.
"Aqueous" just means that the solvent is water.
"Original" means that a solution used to prepare other solutions by dilution.
"Unsaturated" means that the amount of solute dissolved is below the maximum amount that can be dissolved per unit volume.
"Standard solution" = a solution that contains a precisely known concentration of solute (in analytical terms anyway).
