Answer 1

The correct option is D It protects foetus from mechanical shocks.

The haemochorial placenta is the type of placenta in which maternal blood is in direct contact with the chorionic villi which are covered by maternal blood and exchange of gases and nutrients from mother's blood and foetus takes place as observed in humans.

So the correct option is 'It protects foetus from mechanical shocks'
