Column - X (Colloids)	Column - Y (Classification)
(I) Rain cloud	A. Sol
(II) Milk of magnesia	B. Aerosol
(III) Soap suds	C. Gel
(IV) Butter	D. Foam

• A. (I) - A , (II) - B, (III) - C , (IV) - D
• B. (I) - A, (II) - C, (III) - B, (IV) - D
• C. (I) - B, (II) - A, (III) - D, (IV) - C
• D. (I) - B, (II) - A, (III) - C, (IV) - D

Answer 1

Answer: (A)

(I) - A , (II) - B, (III) - C , (IV) - D

A sol is a colloidal solution suspension of very small solid particles in a continuous liquid medium.Ex: Rain clouds.

An aerosol is defined as a colloidal system of solid or liquid particles in a gas.Ex:Milk of megnesia.

A semi-rigid slab or cylinder of an organic polymer used as a medium for the separation of macromolecules is called gel.Saop suds.

Foam is a colloidal system in which the particles are gas bubbles and the medium is a liquid. The term also is applied to material in a lightweight cellular spongy or rigid form.Ex:Butter.

So the correct options are (I) - A (II) - B (III) - C (IV) - D.

Hence option A is correct.
