Brownfields are best described as:

Brownfields are best described as:

• A. Contaminated industrial or commercial sites that may require environmental cleanup before redevelopment or expansion
• B. Undeveloped rural land with no contamination
• C. Parks set aside for recreation
• D. Water treatment facilities undergoing upgrades

Answer: (A)

The main idea is properties with pollutants from past industrial or commercial use where redevelopment or expansion is complicated by the need for environmental cleanup. Brownfields are often in urban areas and hold potential for reuse once contamination is assessed and cleaned up, reducing the pressure to develop untouched rural land and helping revitalize neighborhoods. This description fits best because it emphasizes both the presence of contamination and the redevelopment aspect. The other options describe land with no contamination (greenfield), parks for recreation, or infrastructure upgrades, none of which capture the combination of contamination and redevelopment potential that defines brownfields.
