The correct option is(1) ectoderm and mesoderm
Explanation:
Amnion of mammalian embryo is derived from ectoderm and mesoderm. It is one of the extraembryonic membranes which is formed by the amniogenic cells of ectodermal origin on the inner side and somatopleuric extraembryonic mesoderm on outer side. This membrane acts as a shock absorber for the foetus, regulates foetal body temperature and prevents desiccation.
The origin of other extraembryonic membranes is as follows
