A resposta correta é a alternativa c) Apenas I, II e III estão corretas. As características dos fluidos dilatantes são: I- Eles aumentam sua viscosidade de acordo com a taxa de deformação. II- Eles retornam à viscosidade normal quando em repouso. III- Exemplos de fluidos dilatantes são tinta, petróleo bruto e mel. A alternativa d) está incorreta, pois o gesso é um exemplo de fluido pseudoplástico, não dilatante.
