Correct answer: C. Amniotic fluid
- A. Pericardial fluid
- B. Allantoic fluid
- C. Amniotic fluid
- D. All of these
Explanation
Amniotic fluid plays a crucial role in protecting the developing embryo/fetus against physical trauma. It is a liquid that surrounds the embryo/fetus within the amniotic sac, which is formed by the amnion membrane. The amniotic fluid acts as a cushion, providing a protective barrier and absorbing shocks or impacts that may occur during movement or external forces.

About Embryonic Development
Embryonic development begins after fertilization with cleavage and formation of the morula and blastula, followed by gastrulation and the establishment of germ layers. It includes organ formation, tissue differentiation and early growth, rather than the later increase in size associated with postnatal development.
