Which one of the following foods is rich in vitamin B?

Wheat germ flour is indeed recognized as a rich source of several B vitamins, particularly vitamin B1 (thiamine), vitamin B2 (riboflavin), vitamin B3 (niacin), and vitamin B6 (pyridoxine). The germ of the wheat kernel is where many of the nutrients are stored, making wheat germ flour particularly nutritious and beneficial in supporting energy metabolism and overall health.

While the other foods listed do contain B vitamins, their concentration is lower in comparison to wheat germ flour. Cheddar cheese, while nutritious, primarily offers calcium and protein rather than a significant amount of B vitamins. Chicken breast is a good source of niacin and vitamin B6 but does not have the variety of B vitamins that are found in wheat germ. Bananas, while providing vitamin B6, do not have the range of B vitamins present in wheat germ flour. This makes wheat germ flour a standout option when specifically searching for a food that is rich in multiple B vitamins.
