ovarian failure.
The Correct Answer is C

D. Ovarian failure usually leads to secondary amenorrhea after menarche, rather than primary amenorrhea.

Correct Answer is D
Explanation
Rationale:
A. While the newborn liver has some immaturity, the main reason for vitamin K administration is not liver production alone.
B. Hemolysis of fetal red blood cells does not significantly affect coagulation factor levels requiring vitamin K.
C. Newborns receive vitamin K through breast milk or formula, but the immediate postnatal administration is not due to dietary deficiency.
D. Newborns are born with a sterile gut, lacking the intestinal flora that synthesize vitamin K. This predisposes them to vitamin K deficiency and increases the risk of hemorrhagic disease of the newborn, so prophylactic vitamin K is administered shortly after birth.
