Choose the correct answer from the options given below:

Correct option is B

Introduction:

This question matches types of water pollutants with their specific examples. Water pollutants are substances, organisms, or energy forms that contaminate water bodies, degrading water quality and making it harmful to humans or the environment.

Information Booster:

• A. Disease Causing Agent - II. Coliform Bacteria: Coliform bacteria serve as indicators of faecal contamination, which can cause various diseases.

• B. Oxygen Consuming Waste - III. Animals and Plants in aquatic habitat: Decomposing organic matter from dead organisms consumes dissolved oxygen.

• C. Plant Nutrient - IV. Phosphorous: Phosphorous (and Nitrogen) are key nutrients that lead to eutrophication (excessive plant growth).

• D. Suspended Solids - I. Fine particles of clay: Suspended solids are undissolved particles like clay or silt that make water turbid.

Additional Knowledge:

• Water pollutants are categorized by their impact on water quality and ecosystem.
