  1. AEutrophication
  2. BNitrification
  3. CAmmonification
  4. DBioremediation

Explanation

Bioremediation is the use of microorganisms (bacteria, fungi) to degrade or detoxify pollutants such as pesticides, oil spills, and solvents in soil or water. Eutrophication is nutrient enrichment of water bodies, nitrification converts ammonia to nitrate, and ammonification releases ammonia from organic matter. Hence bioremediation is the correct term.
