Which of the following is a plant source of Vitamin B12?

Vitamin B12, also known as cobalamin, is primarily found in animal products, which poses a challenge for individuals on vegetarian or vegan diets to meet their B12 requirements. However, certain plant-based foods can be fortified with Vitamin B12, providing an essential source for those not consuming animal products.

Fortified cereals are a notable example, as these cereals are specifically enhanced with vitamins and minerals that may lack in a plant-based diet. They often have Vitamin B12 added during manufacturing, making them a reliable, convenient source of this nutrient for those looking to increase their intake without consuming animal-derived foods.

In contrast, spinach, broccoli, and carrots do not naturally contain Vitamin B12. While they provide various other vitamins and minerals that are beneficial for overall nutrition and health, they do not serve as sources of B12. Thus, fortified cereals stand out as the correct choice for plant sources of Vitamin B12.
