Key Details:
An emulsion is a mixture of two immiscible liquids where one is dispersed as tiny droplets in the other, and milk consists of fat globules (dispersed phase) suspended in water (dispersion medium).
Why other options are incorrect:
Suspension: A suspension has solid particles dispersed in a liquid, whereas milk has liquid fat globules dispersed in liquid water.
Solution: A solution is a homogeneous mixture where the solute dissolves completely in the solvent, which is not the case with milk.
Solid solution A solid sol has a solid dispersed in a solid medium, while milk has a liquid dispersed in a liquid.
