A) Gaseous solution                         1) German silver
B) Liquid solution                               2) Milk
C) Solid solution                                3) Sand in water
D) Colloidal solution                         4) Aqueous Alcoholic solution
                                                             5) Air
The correct match is

The correct matches for the given question with its options would be as follows:

In Gaseous solution the solvent is gas. So its correct match would be air.

In Liquid solutions the solvent is liquid, so the correct choice should be the aqueous alcoholic solution as it is water(solute) in nature.                                    

In Solid solution the solvent is solid, So its correct match would be alloys like German silver which are solids dissolved in solids

A colloidal solution is a heterogeneous system in which a dispersed phase is dispersed in the dispersion medium. So, making the correct option to be milk.

Hence, the required matching for the given question is represented by option A)A-5 , B-4, C-1, D-2.
