"Untreated water from a factory flowing into a lake" is an example of point source pollution. 
Why? You can actually point to a specific source- the factory. Runoff isn't considered point source.

If I helped you mark brainliest.
 

Answer: untreated water from a factory flowing to the river.

Explanation: Point source pollution can be defined as the single source by which the polluted water is coming or pollution is coming.

Here the source is factory and the polluted water from the factory is discharged into the lake.This water from the lake can be transferred to other places.  

So, the point source is polluted water from factory
