The correct option is C Meconium
The first intestinal discharge from newborns is meconium, which is a viscous, dark-green substance composed of intestinal epithelial cells, lanugo, mucus, and intestinal secretions (eg, bile). Intestinal secretions, mucosal cells, and solid elements of swallowed amniotic fluid are the 3 major solid constituents of meconium. Water is the major liquid constituent, comprising 85-95% of meconium. Meconium is sterile and does not contain bacteria.
