Among the given nutrients, milk is a poor source of Vitamin C. While milk is known for its high calcium content and is often touted as a good source of protein, it does not naturally contain Vitamin C.

Vitamin C is commonly found in fruits and vegetables such as citrus fruits, strawberries, and bell peppers. It is crucial for the formation of collagen, absorption of iron, and maintaining a healthy immune system. Although milk is an excellent source of calcium, protein, and carbohydrates, it is important to consume a variety of foods to ensure a well-rounded nutrient intake. Therefore, if one is specifically seeking to obtain Vitamin C, they should look beyond milk and incorporate other foods rich in this nutrient into their diet.
