Brief Explanations:

Smoke is a mixture of solid particles (ash, soot etc.) dispersed in a gas (air). A colloid is a heterogeneous mixture in which the dispersed - phase particles have a size between 1 - 1000 nm. The particles in smoke are of this size range and do not settle out quickly like in a suspension. A solution has very small solute particles that are molecular or ionic in size. A compound is a pure substance made of two or more different elements chemically combined. A molecule is the smallest particle of a compound or an element that has the chemical properties of that substance.

Answer:

C. colloid
