Open in App
Solution
The correct option is D Detergents
Detergents that are released from the domestic sewage, as well as the industrial effluents, are the causative pollutants because these result in the increasing the inorganic mineral quantity in the water body. Because of this, the eutrophication occurs. The dissolved oxygen in the water body is decreased and the aquatic life suffers from the hypoxia. Plastic, glass junk and iron junk persist in nature as they are non-biodegradable. Their downhill causes are less as compared to the detergents.Hence, the correct answer is 'Detergents'
