  2. Area

The Correct Answer:

A. An industry’s smokestack is an example of a point type of source.


Any toxic substance can be defined as a chemical that has the ability to cause harm, even in a small amount, to the human population. They are responsible for producing injury or causing harm to the living organism when they come in contact. The transport of these materials or contaminants can occur due to the help of a medium like groundwater, soil, or air.

If any hazardous material has come to the environment from a single source, it can be termed a point source. A smokestack from the factory or transportation of a toxic waste via air or pipe can be called a point source because they are coming from a specific point, i.e., an industry.
