The correct option is B All of above
All the options are causes of industrial pollution
Asbestos:
This pollutant has cancer-causing properties. When inhaled, it can cause illnesses such as asbestosis and some types of cancer.
Nitrates & Phosphates:
These are found in fertilizers, and are often washed from the soils to nearby water bodies. They can cause eutrophication, which can be very problematic to marine environments.
Oils:
Oils form a thick layer on the water surface because they do not dissolve in water. This can stop marine plants receiving enough light for photosynthesis.
