## **Core Concept**
Breast milk provides numerous benefits for infants, including optimal nutrition, immune protection, and reduced risks of various health issues. The composition of breast milk is specifically tailored to meet the nutritional needs of infants, and it contains antibodies that help protect against infections.

## **Why the Correct Answer is Right**
The correct answer includes options a) Better nutrition, b) Less infection, and d) Less allergy. Breast milk is considered the gold standard for infant nutrition because it provides the perfect mix of proteins, fats, carbohydrates, vitamins, and minerals for infants. The antibodies present in breast milk, particularly immunoglobulins, help protect infants from many infections, reducing the risk of respiratory tract infections, ear infections, and diarrhea. Additionally, breastfeeding has been shown to reduce the risk of allergies in infants.

## **Why Each Wrong Option is Incorrect**
- **Option C:** More diarrhea is incorrect because breast milk actually helps reduce the incidence of diarrhea in infants. The antibodies in breast milk help protect against certain pathogens that can cause diarrhea.
- **Option E:** High sodium contents is incorrect because breast milk has an optimal sodium content that is suitable for infants. It does not have high sodium levels compared to cow's milk or other infant formulas, which can be too high for infant kidneys to handle.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is that breast milk is dynamically composed to meet the changing needs of the infant, from birth through weaning. The World Health Organization recommends exclusive breastfeeding for the first six months of life, followed by continued breastfeeding along with appropriate complementary foods for up to two years or beyond.

## **Correct Answer:** B. a, b, d.
