Answer 1

The correct option is C amnion

Amnion consists of trophoblast inside and mesoderm outside. It encloses the amniotic cavity which is filled by the amniotic fluid (which is derived from the fetal kidneys and bladder). The amnion and the amniotic cavity enlarges and nearly surrounds the embryo.

So the correct option is 'Amnion'.
