Morula is the correct answer.
- Embryonic development occurs after the fertilization of ovum with the sperm. The place of fertilization is oviduct in females.
- After fertilization, zygote is formed. Cleavage of zygote results in formation of morula. Morula is characterized by presence of 8 celled mass.
- Subsequent division of morula forms blastula, which is known for presence of blastocoel.
- Next stage is development of gastrula which contains three germinal layers namely ectoderm, endoderm and mesoderm.
