C Correct answer
Explanation

The correct answer is 'Nitrates and Phosphates'. Eutrophication is the process where water bodies become overly enriched with minerals and nutrients, leading to excessive plant growth. Nitrates and phosphates from agricultural runoff and sewage are the primary nutrients causing this. 'Silt load' causes turbidity, 'sewage' contains nutrients but the question asks what accumulation causes eutrophication (the nutrients themselves), and 'vegetation' is the result not the cause.
