Answer: (D)
Solution
A foam is a gas dispersed in a liquid, the everyday example being the froth of soap lather. A gel is a liquid held in a solid network, as in jellies. An aerosol is a fine solid (or liquid) dispersed in a gas, typified by smoke. An emulsion is one liquid dispersed in another, as in milk, where fat is dispersed in water. Matching accordingly, foam goes with froth, gel with jellies, aerosol with smoke and emulsion with milk.
