The correct option is C Thiamine and other types of vitamin B
Wernicke's syndrome is caused by the lack of vitamin B1 and is common in people with alcoholism. It causes brain damage in the lower parts of the brain. So, vitamin B1 or thiamine and other vitamins must be taken to treat Wernicke's syndrome.
Thus, the correct answer is option (C), 'Thiamine and other types of vitamin B'.
