Final Answer :

Explanation :
Vitamin B12 deficiency leads to pernicious anemia, characterized by the body's inability to absorb vitamin B12 due to the lack of intrinsic factor, and can also cause neurological issues, but it does not directly cause irreversible liver damage; that part of the option is incorrect.
