Final answer:
The material in question would be most suitable for sound insulation due to its nonporous and impervious nature. It would also serve well as a thermal insulator, but it would not be ideal for water filtration or electrical conduction.
Step-by-step explanation:
The material that is relatively nonporous and impervious is typically not used for water filtration, which requires porosity to allow water to pass through while filtering out contaminants. Instead, such a material would be more suitable for applications that require an obstruction of flow or transfer, such as sound insulation, where the goal is to prevent the transmission of sound waves.
Regarding thermal and electrical properties, such a material described as nonporous and impervious would likely be a good thermal insulator, given its poor thermal conductivity. This means it would be effective at reducing heat flow into and out of a structure (Option C). As for electrical conduction (Option D), this material would act as an insulator, preventing the movement of charge and thus not favoring electrical conduction. Materials that are more nonconductive than conductors, such as glass or ceramics, are typical insulators. These materials have electrons and ions bound in their structure, restricting movement and making them poor electrical conductors.
