Answer 2

Do you have any ideas?

Answer 3

I was thinking c :P

Answer 4

Actually, it would be D. Volcanic eruptions can release excess amounts of phosphorous and nitrogen, not to mention magma. Earthquakes can rupture oil pockets, and create tsunamis and fires. Algae blooms kill fish by producing bio-poisons and using up all the water's oxygen, which fish need.
