During embryogeny in a typical dicotyledonous plant, what is the correct chronological sequence of developmental stages from the zygote to the mature embryo?

1. A
   Zygote \( \rightarrow \) Globular embryo \( \rightarrow \) Proembryo \( \rightarrow \) Heart-shaped embryo \( \rightarrow \) Mature embryo
2. B
   Zygote \( \rightarrow \) Proembryo \( \rightarrow \) Heart-shaped embryo \( \rightarrow \) Globular embryo \( \rightarrow \) Mature embryo
3. C
   Zygote \( \rightarrow \) Proembryo \( \rightarrow \) Globular embryo \( \rightarrow \) Heart-shaped embryo \( \rightarrow \) Mature embryo
4. D
   Zygote \( \rightarrow \) Heart-shaped embryo \( \rightarrow \) Globular embryo \( \rightarrow \) Proembryo \( \rightarrow \) Mature embryo
