The correct answer is (d) West Bengal.
Arsenic is a naturally occurring element that can be found in groundwater, soil, and air. It is a metalloid that is not essential for human health and can be toxic in small amounts. Arsenic poisoning can cause a variety of health problems, including skin lesions, cancer, and neurological problems.
West Bengal is the state in India with the highest levels of arsenic contamination in groundwater. According to the World Health Organization, an estimated 30 million people in West Bengal are at risk of arsenic poisoning. The contamination is caused by natural geological processes, and it is not possible to remove arsenic from groundwater once it has been contaminated.
