Answering the Multiple-Choice Question

In this question, we need to identify which vitamin is exclusively found in foods derived from animals. Let’s evaluate each option:

1. Riboflavin (Vitamin B2): Found in both animal and plant foods.
2. Vitamin B12: Primarily found in animal-based foods such as meat, eggs, and dairy products. It is not found in plant foods in sufficient amounts.
3. The inactive form of vitamin A: While preformed vitamin A (retinol) is found in animal sources, provitamin A carotenoids are found in plant sources.
4. Pantothenic acid (Vitamin B5): Present in both animal and plant sources.

Conclusion

The correct answer is b. Vitamin B12, as it is the only vitamin on this list that is found almost exclusively in animal products.
