The correct answer is option 1: Copper. Copper toxicity can lead to liver cirrhosis. Cirrhosis is a condition where scar tissue replaces healthy liver tissue, leading to liver dysfunction. Excessive intake of copper, either through contaminated food or drinking water, can accumulate in the liver and cause damage over time. This toxicity can trigger inflammation and oxidative stress, ultimately leading to the development of cirrhosis. It is important to note that while copper is an essential mineral needed in small amounts for proper bodily functions, excessive levels can be harmful. Liver function tests and monitoring of copper levels in the blood can help identify and manage copper toxicity.
