What are the potential health effects of consuming water with high arsenic levels?

The correct choice highlights the serious health implications associated with long-term exposure to water contaminated with high levels of arsenic. Prolonged ingestion of arsenic can lead to a variety of significant health issues, including an increased risk of cancers, specifically skin, bladder, and lung cancers. Additionally, chronic exposure can result in skin lesions, which manifest as changes in skin color, development of warts, or thickening of the skin.

The health risks associated with arsenic are well-documented and arise from its ability to interfere with cellular processes and promote the development of malignancies over time. Understanding these risks emphasizes the importance of monitoring arsenic levels in drinking water, particularly in areas where natural or industrial contamination is a concern. The other options do not accurately reflect the hazards posed by arsenic, as short-term digestive issues and immediate allergic reactions are not typical effects, and enhanced immune response would not arise from arsenic exposure.
