The correct option is B Expressed breast milk cannot be stored at room temperature for more than 2 hrs.
Colostrum (also called as first milk) is the thin yellowish fluid secreted by the mammary glands at the time of parturition and which precedes the production of true milk. It provides a nursing infant with essential nutrients and infection-fighting antibodies (called as immunoglobulin) to protect the newborn against disease. IgA is the major immunoglobulin in colostrum. It protects from inhaled and ingested pathogens.
