Which category is associated with pollution listings that relate to the indoor environment?

• A. Indoor
• B. Air
• C. Water
• D. Solid

Answer: (A)

The main idea is that pollution listings are organized by the environment they pertain to. When the focus is contaminants that exist or affect spaces inside buildings, the relevant tag is the Indoor category. This category covers hazards encountered in enclosed settings—things like indoor air quality, dust, mold, and VOCs off-gassing from furnishings and building materials—where people are exposed in daily life or work. The other categories refer to the medium of pollution in a broader sense: Air for pollutants in the air (often outdoors or general air quality), Water for pollutants in water, and Solid for solid wastes. Since the question specifically targets pollutants related to the indoor environment, the Indoor category is the appropriate choice.
