What would occur if a fetus's villi tissue ruptured? 

The maternal tissue of the placenta would be damaged, causing bleeding.
The maternal and fetal blood would mix, causing an immune reaction.
The umbilical vein would be blocked, preventing waste export from the fetus.
The umbilical artery would be blocked, preventing oxygen import to the fetus.

Answer:

The correct answer is option A, The maternal tissue of the placenta would be damaged, causing bleeding

Step-by-step explanation:

Villis are basically trophoblast cells which are connected to the maternal tissue and are surrounded by maternal blood. When a villi bursts, the veins and arteries of the placenta that passes through it get ruptured and bleeding starts. The capillary wall associated with the villis also get ruptured and lead to hemorrhage condition and sudden anoxia.

The placenta is developed in the uterus during the pregnancy. This structure provides oxygen and nutrients to the growing baby and removes waste products from the baby's blood.
The diagram clearly shows the position of placenta around the baby and is considered as its protection.
