Option 1 : Only 1

Explanation:

Eutrophication: It is an enrichment of water by nutrient salts that causes structural changes to the ecosystem. It results in the reduction of dissolved oxygen.

Compounds that contain nitrogen and phosphorus (fertilizers) drive eutrophication. These nutrients are generally not toxic.

Effects:

In the process of eutrophication the demand for dissolved oxygen in water increases, while the quantity of dissolved oxygen in water decreases
They can have a large impact on the health of rivers and estuaries such as increased production of algae and aquatic plants, depletion of fish species, general deterioration of water quality.
