Question

Which of the following embryonic stages is correctly ordered chronologically?
Options
A Gastrula → Zygote → Blastula
B Zygote → Morula → Blastula → Gastrula
Correct Answer
C Blastula → Cleavage → Zygote
D Neurula → Blastula → Zygote
Correct Answer

Option B is the correct answer.

Detailed Explanation

The correct order is: Fertilization forms a Zygote. Cleavage divisions produce a solid Morula. Further division and cavity formation create a hollow Blastula. Gastrulation then forms the three-layered Gastrula.

Hint

Start with a single cell and progress to a structured, layered embryo.
