Option 3 : D only

Groundwater is the water present beneath Earth's surface in rock and soil pore spaces and in the fractures of rock formations. About 30 percent of all readily available freshwater in the world is groundwater.

Nonpoint source pollution can include Excess fertilizers, herbicides, and insecticides from agricultural lands and residential areas.
Oil, grease, and toxic chemicals from urban runoff and energy production.
Sediment from improperly managed construction sites, crop and forest lands, and eroding streambanks.

Hence 'nonpoint source(s)' of groundwater contamination is agricultural land. ie. option D only.

Groundwater contamination occurs when man-made products such as gasoline, oil, road salts, and chemicals get into the groundwater and cause it to become unsafe and unfit for human use.
Materials from the land's surface can move through the soil and end up in the groundwater.
Drinking contaminated groundwater can have serious health effects. Diseases such as hepatitis and dysentery may be caused by contamination from septic tank waste.
Poisoning may be caused by toxins that have leached into well water supplies. Wildlife can also be harmed by contaminated groundwater.
