your answer is Nonpoint source pollution because this occurs due to a spreading of contaminants into a larger area and the actual source of the pollution can not be defined.
some examples are air, water and soil pollution. Mainly from vehicles the air is being polluted and we can not trace it.
same happens in case of water and soil many hospitals, factories, labs and even homes discard some pollutants and we can't find a single source.
if the source is only single place like a particular hospital or handicraft factory than we can call it as a point source pollution.
