Correct Answer: C

Rationale: Physiologic jaundice in a newborn, also known as neonatal jaundice, is a common condition in newborns characterized by yellow discoloration of the skin and eyes due to elevated levels of bilirubin in the blood. In newborns, the liver is not fully developed, leading to an inability to efficiently process and excrete bilirubin. Bilirubin is a byproduct of the breakdown of red blood cells, and in newborns, the liver may not yet be able to efficiently bind bilirubin for excretion, leading to its accumulation in the blood and manifesting as jaundice. Physiologic jaundice typically occurs around 2 to 4 days after birth and usually resolves on its own without treatment as the baby's liver matures and becomes more efficient at processing bilirubin.
