उत्तर
Extra embryonic membrane that immediately surrounds and protects the embryo is Amnion.
Explanation:
The amnion is the extra-embryonic membrane that directly surrounds and protects the embryo, enclosing it in amniotic fluid which acts as a shock absorber. The chorion is the outermost layer, the yolk sac provides nutrition, and the trophoblast is involved in implantation, none directly enclose the embryo.
