Explanation:

• The Total Maximum Daily Load (TMDL) criteria are used to address eutrophication from non - point source pollution. TMDL sets the maximum amount of a pollutant that a water body can receive and still meet water quality standards.
• The Water Pollution Control Act (A) is a more general act. The National Pollution Discharge Elimination System (C) mainly focuses on point - source pollution. There is no "Nonpoint Source Pollution Abatement Act" (D) as a commonly known major regulatory act for this specific purpose.

Answer:

B. Total maximum daily load criteria
