c. Vitamin B-12

d. Riboflavin

e. Vitamin E 12

Option-B

Explanation:

Niacin is a form of water-soluble vitamin B3 which is taken as medication to treat the high level of bad cholesterol called LDL.

To treat this cholesterol level, very high level of vitamin B3 is suggested but this poses a high risk to the human body like it can damage the liver and facial flushing in which the face appears reddish as this vitamin dilates the blood vessels in the face.
