b. Two veins and one artery
c. Two arteries and one vein
d. Two arteries and two veins
ANS: C
The umbilical cord contains two arteries and one vein to transport blood between the fetus and the placenta.

Two arteries instead of one is considered normal; this infant would require further assessment for other anomalies.
