Vitamin C can be found in which of the following sources?

The correct answer is B: plants. Vitamin C, also known as ascorbic acid, is commonly found in fruits and vegetables, which are plant-based sources. Citrus fruits like oranges, strawberries, and vegetables like bell peppers and broccoli are rich in vitamin C. Plants produce vitamin C through their metabolism, making them a primary source of this essential nutrient in our diet. Choosing options A, C, or D is incorrect as minerals, animal sources, and solvents do not naturally contain vitamin C. Minerals are inorganic compounds, animal sources typically do not produce vitamin C, and solvents are chemicals used for dissolving substances. Hence, option B is the correct answer as it aligns with the natural sources of vitamin C.
