Question
What is the correct sequence of early embryonic development?
Correct Answer
Option A is the correct answer.
Detailed Explanation
Fertilization forms a zygote, which undergoes cleavage (cell division) to become a morula (solid ball). A fluid-filled cavity forms, creating a blastula. Gastrulation then forms the germ layers.
Hint
It starts with a single cell and progresses to a structured, multi-layered embryo.
