Which of the following can help in water conservation?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. Rainwater harvesting.
The correct option is Rainwater harvesting, as it is one of the most effective methods of water conservation. This technique involves collecting and storing rainwater from rooftops, surfaces, or catchments for future use. It helps recharge groundwater, reduces dependency on external water sources, and ensures water availability during dry seasons. While setting up water treatment plants improves water quality, it does not directly conserve water. Halving the drinking water supply or harming animal populations are neither practical nor ethical solutions, making rainwater harvesting the most sustainable approach.
