A. 200
B. 500
C. 133
D. 250

Answer 1

Hint: - India’s water level is fastly draining in recent years as the demands are increasing day by day.
- It is estimated that India's cumulative renewable water supplies are 1,897 sq km per annum.
- By 2025, it is expected that India will become one of those countries with total water shortages.

Complete Answer:
Present condition: As India has heavy precipitation every year but there is heavy demand for water resources for industrialisation too. The water demand is also increasing because of increasing population and increasing agricultural activities. India receives 4% of global precipitation but ranks 133 in the world in terms of water availability per person per year.

Causes leading to water scarcity: the number of water supplies varies over time and space, mostly due to seasonal and annual rainfall fluctuations, but water scarcity is primarily caused by over-exploitation, inappropriate usage and unequal access between various social classes to water.

 Major concerns: If India’s water level decreases around 1000 or 1100 cubic meters then India will be declared as a water stressed country, which is a matter of concern. India is mainly suffering from groundwater scarcity and the state Maharashtra is most affected by water scarcity where 6 of 17 reservoirs are dried up. Day by day the population is increasing which leads to an increase in demands but the resources are limited which is the aim cause of water shortage in India.

Thus from the above discussion, it can be concluded that the correct answer is option C.

Note: - Sringaverapura near Allahabad had a sophisticated water harvest network channelling the flood water of the Ganga river in the first century B.C.
- The first state in India to make the rooftop rainwater harvesting structure compulsory for all houses in the state is Tamil Nadu. To punish the violators, there are specific legal laws.
