Answer:
Option (C)
Step-by-step explanation:
Water pollution has become a great issue in the present generation. The water present on the surface of the earth is constantly affected due to anthropogenic activities. The freshwater covers only 3% of the total water present on earth.
India is a developing country that is comprised of a large number of industries and factories, producing numerous varieties of materials. These industries use various types of toxic and harmful chemicals that produce a large amount of waste materials comprised of these chemicals. These waste materials are mixed with the river water and streams, thereby contaminating it. In addition to this, the household waste, such as the sewage waste, solid and liquid garbage materials are also thrown to the rivers and lakes, by the people as a result of which the water is highly polluted.
Thus, the chemicals released by the industries and the poor sewage treatment are the two prime factors that cause the majority of water pollution on earth.
Hence, the correct answer is option (C).
