Explanation:

The 1972 Clean Water Act established uniform national water quality standards that all U.S. states had to meet, marking a key federal framework for water protection. Option A relates to oil spill penalties which are more associated with other laws like the Oil Pollution Act. Option B is the focus of the Safe Drinking Water Act, not the 1972 Clean Water Act. Option D's Lake Erie cleanup was not a core mandate of this specific act.

Answer:

C. standardized water quality for all states
