A. Moon is between the Sun and Earth
Explanation:
The new moon stage is the faze in which we can not see the Moon from Earth.

The reason for this is that the Moon is located between the Sun and the Earth.

These are the three primary germ layers and give rise to various tissues and body organs.
Endoderm of the embryo give rise to epithelial lining of gastrointestinal tract (except the buccal cavity), respiratory tracts and other organs such as gallbladder, liver,etc. Mesoderm forms connective tissues such as bones as well as muscles and peritoneum. All the tissues of nervous system and epidermis of skin are derived from ectoderm.
