B Correct answer
Explanation

Eutrophication is characterized by excessive plant and algal growth due to the increased availability of one or more limiting growth factors needed for photosynthesis such as sunlight, carbon dioxide and nutrient fertilizers. This can be a problem in marine habitats such as lakes, as it can cause algal blooms.
