Based on the "EMBRYONIC DEVELOPMENT" diagram, which sequence correctly describes the primary stages of embryonic development in animals, starting from fertilization?

  • A: Fertilization → Cleavage → Gastrulation → Organogenesis
  • B: Cleavage → Fertilization → Gastrulation → Organogenesis
  • C: Fertilization → Gastrulation → Cleavage → Organogenesis
  • D: Fertilization → Cleavage → Organogenesis → Gastrulation

Explanation

The diagram clearly shows the sequence of events starting from Fertilization, followed by Cleavage, then Gastrulation, and finally Organogenesis. Metamorphosis is a later stage in the frog life cycle.
