Best answer
The correct answer is (a) Ceramics, glass, silicon

Best explanation: During vacuum evaporation, the gaseous material deposits on the substrate and its surroundings as film. Various substrate materials are used, depending on the subsequent application of the film that is to be deposited. The typical substrates used are ceramics (Al2O3), glass, alkali halides, silicon, germanium, etc.
