Correct Answer: Overexploitation of ground water in the affected areas

Solution : The correct answer is Overexploitation of ground water in the affected areas .

Arsenic, a naturally occurring element present in the Earth's crust, is ubiquitously distributed in the environment, encompassing the atmosphere, bodies of water, and terrestrial regions. In its inorganic state, it poses severe toxicity risks. Arsenic is naturally present in deep underground water reservoirs, and when there is extensive extraction of groundwater, it can lead to the release of arsenic into the surrounding environment. Additionally, sources of arsenic pollution include high-temperature industrial processes such as those seen in coal-fired power plants, volcanic activity, wildfires, and similar phenomena.
