Which of the following is an antidote for Copper poisoning?

Pencillamine is utilized as an antidote for copper poisoning due to its chelating properties, which enable it to bind copper ions in the body. This chelation process facilitates the removal of excess copper, allowing the body to excrete it more effectively through the urine. Copper poisoning can lead to serious health issues, including liver and kidney damage, but the use of Pencillamine helps mitigate these effects by reducing the levels of toxic copper in the system.

Other substances mentioned, such as activated charcoal, are effective in certain types of poisoning scenarios, particularly for organic compounds, but they do not target heavy metals like copper. N-acetylcysteine is specific for acetaminophen (paracetamol) overdose, while sodium bicarbonate is commonly used for metabolic acidosis and is not relevant in copper poisoning. Thus, Pencillamine’s targeted action as a chelating agent makes it the appropriate treatment in this context.
