Human wastewater results in which water-pollution problem? i. decomposition of organic matter reduces dissolved oxygen levels. ii. decomposition of organic matter releases great quantities of nutrients. iii. pathogenic organisms are carried to surface waters.

The correct answer is - all the options.

Explanation:

Any water that is used by humans or affected by humans is termed as wastewater. It includes water that comes from domestic households, agricultural and industrial water that can lead to pollution to the lakes, rivers, and other water bodies.

Decomposition of the waste present in the water release a high quantity of minerals that affect the environment and organisms.

Thus, the correct answer is - all the options.
