Answer: C
Such coatings are called lacquers.
A lacquer is a solution of a film-former, such as nitrocellulose or an acrylic resin, in a volatile solvent. It dries quickly by simple evaporation of the solvent, with no chemical change, and the dried film can be redissolved by the same solvent.
A varnish dries by oxidation and polymerisation of drying oils and resins. The vehicle is the liquid part of a paint that carries the pigment, and resins are the film-forming materials themselves, not a class of coatings defined by how they dry.
