With reference to the nutritional value of milk, consider the following statements: 1. It is considered an incomplete food as it lacks calcium. 2. It provides nourishment to infants. 3. It is a rich source of proteins and calcium. Which of the statements given above is/are correct?

The correct option is (c). Explanation Milk is a nutrient-dense food that serves as a primary source of nutrition for mammals during early development. It contains a complex mixture of lipids, carbohydrates, proteins, vitamins, and minerals. - Statement 1 is Incorrect: Milk is not considered incomplete due to a lack of calcium; on the contrary, it is one of the richest dietary sources of calcium. However, milk is often cited as being deficient in Iron and Vitamin C (Ascorbic acid). The statement is false because it incorrectly identifies calcium as the missing nutrient. - Statement 2 is Correct: Milk provides complete nourishment to infants during the initial months of life. It contains water, proteins, fats, lactose (milk sugar), and essential micronutrients required for the rapid growth and development of the infant. - Statement 3 is Correct: Milk is a rich source of high-biological-value proteins, primarily casein and whey proteins. It is also a significant source of calcium and phosphorus, which are essential for bone formation and maintenance. Key Takeaway: While milk is a rich source of proteins, calcium, and phosphorus, it is notably poor in Iron and Vitamin C.
