Niacin is classified as which of the following?

Explanation:
Niacin is a B vitamin (specifically vitamin B3). It functions as a coenzyme in redox reactions, forming NAD and NADP, which are essential for energy production from carbohydrates, fats, and proteins. This role places it in the B vitamin group rather than with fat-soluble vitamins like A and D or with vitamin C, which has different functions as an antioxidant.
