Among the following options, which of the following is an example of point source pollution?
Agricultural runoff
Industrial effluent
Oil spills
Acid rain
Point source pollution refers to the pollution that can be traced back to a single identifiable source, such as a pipe or outfall from an industrial facility. Industrial effluent is an example of point source pollution because it is discharged from a single source, such as a factory or industrial plant. Therefore, option B is the correct answer to the above question.
Option 1 is incorrect because agricultural runoff is an example of non-point source pollution.
Option 3 is incorrect because oil spills can come from a variety of sources, making it difficult to identify a single identifiable source.
Option 4 is incorrect because acid rain is a form of atmospheric pollution that can come from a variety of sources, making it difficult to identify a single identifiable source.
