Explanation:

Only statements 1,2&3 are correct.

• Bilirubin is made by the breakdown of red blood cells. It’s hard for babies to get rid of bilirubin at first. It can build up in their blood, tissues, and fluids.
• Bilirubin has a color. It makes a baby’s skin, eyes, and other tissues turn yellow (jaundice). Jaundice may first appear when your baby is born. Or it may also show up any time after birth.
• Bilirubin is also excreted from the liver, and intestinal bacteria catabolize it in the gut to urobilinoids, which can also be reabsorbed through the hepatic portal vein surrounding the intestine.

• The liver is still developing in a newborn, hence, the load of bilirubin might be high due to slower metabolism as well. Higher rates of RBCs or red blood cells in newborns result in increased bilirubin in their system. The short life of the corpuscles also adds up to the bilirubin production.

• New Borns have an immature hepatic system for the uptake, conjugation, and secretion of bilirubin.

• Neonates do not have enzyme UDP glucurnyl transferase, due to this hydrolysis of conjugated bilirubin increases, which is then reabsorbed by the intestine and recycled into circulation. 

• However, Mothers milk does not contain a high amount of bilirubin,  it is rich in protein, sugar, vitamins and minerals. But there is an another type of jaundice called Breast Milk Jaundice that persists after physiologic jaundice subsides in an otherwise healthy baby. 

• "Breast milk Jaundice" must also be differentiated from "breastfeeding jaundice", which is caused due to insufficient intake of milk. As an adequate amount of milk causes an increase in baby's bowel movements and helps in secreting the buildup of bilirubin. 

Hence option 1st is correct.
