The toxicity of which of the following heavy metals leads to Liver cirrhosis

The correct answer is A) Copper.

Copper toxicity can lead to liver cirrhosis. The liver is responsible for processing and eliminating excess copper from the body, but in cases of copper toxicity, the liver can become overwhelmed and damaged. This can lead to liver cirrhosis, a condition in which scar tissue forms in the liver and can ultimately lead to liver failure. Lead toxicity can cause damage to the brain, kidneys, and other organs, while mercury toxicity can lead to neurological damage. Zinc toxicity is rare, but can cause gastrointestinal upset and other symptoms.
