Answer: (A)

Verified step by step guidance

1. Understand the context of the question: Breastfeeding is widely studied in biology and medicine for its impact on infant health and development. The goal is to identify the scientifically supported outcome of breastfeeding from the options provided.
2. Review the biological benefits of breastfeeding: Breast milk contains antibodies (such as IgA) and other immune-boosting components that help protect infants from infections and support the development of their immune system.
3. Analyze the options: Evaluate each choice based on scientific evidence. For example, 'Enhanced immune system development' aligns with the known benefits of breastfeeding, while 'Higher incidence of type 1 diabetes,' 'Increased risk of allergies,' and 'Delayed cognitive development' are not supported by research as outcomes of breastfeeding.
4. Consider the role of breastfeeding in immune system development: Breastfeeding provides passive immunity and promotes the maturation of the infant's immune system, which is a well-established benefit.
5. Select the correct answer based on evidence: Based on the scientific understanding of breastfeeding, the correct answer is 'Enhanced immune system development.'
