A Correct answer
Explanation

Inorganic fertilizers from Midwestern farms wash down the Mississippi River, carrying nitrogen and phosphorus into the Gulf of Mexico. This causes algal blooms that deplete oxygen, creating a 'dead zone' (hypoxia) where marine life cannot survive. Note: option D has a typo ('Gulf' misspelled as 'Guld').
