<u>ANSWER:</u>

The correct order is- Zygote, Blastula, Gastrula, Fetus.

<u>EXPLANATION:</u>

The embryo develops from the zygote which is formed when the gametes fuse in the process of "fertilization".
The zygote undergoes cell division to form blastula which is a "ball of cells".
Gastrula leads to the rearrangement of cells of the blastula into three layers that differentiate into different systems of organ.
The last stage is the fetus which then develops into a baby.
