Answer: (A)

The acronym NAAQS stands for National Ambient Air Quality Standards. This term refers to the standards set by the Environmental Protection Agency (EPA) under the Clean Air Act that establish acceptable levels of pollutants in the ambient air. These standards are designed to protect public health and the environment by regulating harmful pollutants such as particulate matter, ozone, and sulfur dioxide, ensuring that air quality is maintained at a level that is safe for the general population, including sensitive groups such as children and those with preexisting health conditions. Understanding NAAQS is critical for environmental awareness and for promoting clean air initiatives.
