The Correct Option is B
Solution and Explanation
Step 1: Concept
Colostrum is the yellowish fluid secreted by mammary glands during the initial few days of lactation after childbirth.
Step 2: Meaning
It serves as the first form of protection for a newborn, providing essential nutrients and immune support.
Step 3: Analysis
While colostrum contains proteins and vitamins, its most critical biological component is a high concentration of Immunoglobulin A (IgA).
Step 4: Conclusion
These IgA antibodies provide passive immunity to the infant, protecting the infant's digestive and respiratory tracts from pathogens. Final Answer: (B)
