Answer 1

B) Drawing food for the developing cells

Answer 2

The main function of trophectoderm in mammalian embryo is drawing food for the developing cells.

* It is because a trophectoderm helps in formation of the placenta and thereby forms a bridge between the mother and fetus.

* It is an extra embryonic tissue which forms supporting structures such as membranes, placenta, etc.

* Therefore, it helps in passage of food and nutrients from the mother to the fetus and vice-versa.
