The name for any matter in the water that renders it undesirable for human use is which term?

• A. Purification
• B. Pollution
• C. Sedimentation
• D. Contamination

Answer: (B)

Water pollution describes the presence of substances in water that degrade its quality and make it unsuitable for human use. It covers chemical, biological, and physical contaminants from various sources, explaining why the water isn’t fit for drinking, recreation, or supporting ecosystems. Purification and sedimentation are processes used to improve water quality, not the condition itself. Contamination refers to the presence of specific contaminants, but pollution is the broader term that best captures the idea of any matter making water undesirable for use.
