Giải đáp
Đáp án đúng là C. resource
The underlined part that needs correction is resource. It should be source.
Water pollution is categorized into point source, non-point source, and groundwater. Point source pollution comes from a single, identifiable source, such as a factory or sewage treatment plant. Non-point source pollution comes from many diffuse sources, such as agricultural runoff and stormwater runoff.
Source is the correct word to use because it refers to the origin of something. In this case, the origin of the pollution is either a single point or many diffuse points.
Resource is a noun that refers to something that is useful or valuable. It is not the correct word to use in this context because it does not make sense to say that water pollution is a resource.
