When too many fertilizers enter a body of water, an uncontrolled growth of algae may result. the algae consume all of the dissolved oxygen, killing marine life. this is called a ozone pollution b acid rain c eutrophication d toxic spillage

I think that it might be eutrophication because it is a process where, if farmers use too much fertilisers in water, oxygen is depleted and underwater organisms die.

Hope this helps you out!
