The correct option is B
It is called drinking water or water fit for human consumption to water that can be consumed without restriction to drink or prepare food.
In areas with intensive agricultural use it is increasingly difficult to find wells whose water conforms to the requirements of the standards. Especially the values of nitrates and nitrites, in addition to the concentrations of phytosanitary compounds, often exceed the threshold of what is allowed. The same goes for the industries that contaminate drinking water supplies.
