Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: The umbilical cord connects the fetus to the placenta and carries the umbilical vessels embedded in a gelatinous matrix.
Step 2: That matrix is Wharton's jelly, which cushions and supports the vessels and prevents kinking, so option B is correct.
Step 3: The cord has two arteries and one vein, not two veins and one artery, so option C is wrong. Nutrient and oxygen-rich blood reaches the fetus through the umbilical vein, not an artery, so option A is incorrect.
