Pollution is defined as?

• A. The process of cleaning water
• B. The removal of pollutants
• C. The natural state of the environment
• D. Release of harmful materials into the environment

Answer: (D)

Pollution means introducing substances or energy into air, water, or soil that harm living things or disrupt ecosystems. The phrase "release of harmful materials into the environment" matches this idea, because it describes putting substances into the environment that can cause damage—like emissions from cars, chemical spills, plastic waste, or loud noise. These are acts that harm health or degrade habitats. In contrast, cleaning water or removing pollutants are actions that reduce pollution, and the natural state of the environment is not pollution.
