A resposta correta é a alternativa "a. I, II, and III are correct." As propriedades dos polímeros são: I. Eles são compostos orgânicos - plásticos ou borrachas. II. Eles são feitos de carbono, H e outros elementos não metálicos. III. Eles são, em geral, moléculas grandes (macromoléculas). A propriedade de baixa densidade mencionada na alternativa IV não é uma característica geral dos polímeros, portanto, a alternativa correta é a a. I, II e III estão corretas.
