Read the passage and answer the questions that follow.
Given the precarious condition of its ground and surface water resources (rivers, stream, lakes, wetlands and reservoirs). India could be a water-scarce country in the next 40 years. With 1,486 cubic meters (~1.5 million litres) of water available per person, per annum, India falls in the water stressed category. A dip below 1000 cubic meters per person, per annum will push it into the water-scarce category.
The manner of water consumption also compounds the problem. Central Ground Water Board (CGWB) statistics show the indiscriminate use of ground water turned 4% of the total 7,089 assessed units in the country critical in 2022 while 14% were assessed as over-exploited. The situation was worse in 2017 when 17% of the units were over-exploited. Various recharge and conservation efforts have borne fruit but the number of such units remain high in states like Punjab, Rajasthan, Haryana, Delhi, Tamil Nadu and Karnataka.
In India,87% of groundwater is extracted for irrigation and experts say excess withdrawal round the year may be the biggest reason for depletion, as the recharge primarily happens in the monsoon. On the other hand encroachment of water bodies and the discharge of untreated waste water into rivers and streams have reduced the surface water resources.
Identify the factors responsible for depletion of water resources.
A. High consumption of water in agricultural sector
B. High consumption of water in Commercial sector
C. Encroachment of water bodies
D. Excessive water use in domestic sector
E. Discharge of untreated waste water in rivers and streams.

Show answer & explanation
Correct answer: D
Concept
In a passage-based multiple-statement question, classify each statement only by evidence explicitly given in the passage. Do not add a cause merely because it is generally plausible.
Then form the supported set and compare that exact set with the offered combinations.
Application
Statement A is supported: the passage says that 87% of groundwater extraction is for irrigation and links excess withdrawal to depletion.
Statement B is not identified: the passage does not name commercial-sector water consumption as a cause.
Statement C is supported: encroachment of water bodies is said to reduce surface-water resources.
Statement D is not identified: the passage does not attribute depletion to excessive domestic water use.
Statement E is supported: discharge of untreated wastewater into rivers and streams is said to reduce surface-water resources.
Cross-check
The supported set is A, C and E. The offered combination that matches this set exactly is “A, C & E only.”
