The key idea is recognizing a label that names the typical contaminants found in groundwater. Fertilizers, pesticides, gasoline, and solvents are common substances that can leach from soil into groundwater, becoming recognizable as a group of pollutants. The phrase that best captures this idea is Common Groundwater Pollutants, because it explicitly identifies the types of contaminants most frequently encountered in groundwater.

Dissolved Oxygen Levels describe how much oxygen is present in the water, not a set of pollutants. Fracking refers to a drilling technique and is not a pollutant category itself. Groundwater Pollution describes the condition of groundwater being contaminated but does not specify the particular pollutants. Thus, Common Groundwater Pollutants is the precise label for this set of substances.
