  1. A
    Algal bloom
  2. B
    Eutrophication
  3. C
    Fermentation
  4. D
    Both (A) and (B)

Solution & Step-by-step Explanation

Eutrophication is the nutrient enrichment of water bodies which stimulates an excessive, profuse growth of aquatic plants and algae. This rapid accumulation of phytoplankton populations is directly characterized as an algal bloom, which noticeably discolors the water body. Therefore, both concepts are inextricably linked to this phenomenon.
