Which food is noted for being rich in vitamin B?

The food noted for being rich in vitamin B is potatoes. Potatoes are an excellent source of several B vitamins, particularly B6 (pyridoxine) and B3 (niacin). These vitamins play crucial roles in energy metabolism and the proper functioning of the nervous system. While carrots, tomatoes, and oranges do contain some B vitamins, they are generally not as well-known for their vitamin B content as potatoes. This distinction makes potatoes the correct choice for this question, emphasizing their nutritional significance in providing essential B vitamins that support overall health.
