An example of a coenzyme is which of the following?

Explanation:
Coenzymes are organic molecules that bind to enzymes and help them carry out chemical reactions. They’re typically derived from vitamins, acting as carriers for electrons, acyl groups, or other functional groups needed during catalysis. That’s why vitamins are the best fit here: many well-known coenzymes come from vitamins, such as NAD+ and FAD derived from niacin and riboflavin, or coenzyme A derived from pantothenic acid. Minerals can serve as inorganic cofactors, but they’re not coenzymes. Carbohydrates and proteins aren’t coenzymes either.
