The correct sequence in the formation of a baby is as follows. Zygote → Embryo → Foetus → Baby
- Zygote: The fertilized egg, formed after the sperm and egg fuse.
- Embryo: The early stage of development after the zygote, where the basic body structures begin to form.
- Foetus: The later stage of development, where the organism starts to resemble a baby and organs continue to develop.
- Baby: The final stage after birth, when the organism is fully developed and capable of independent life.

Understanding the Developmental Stages
The correct sequence of human development is crucial for understanding how life begins and progresses. The correct order is:
Zygote → Embryo → Foetus → Baby
1. Zygote
- The zygote is the initial cell formed when a sperm fertilizes an egg.
- It contains genetic material from both parents and is the beginning of a new organism.
2. Embryo
- After a few days, the zygote undergoes cell division and becomes an embryo.
- This stage lasts until about the 8th week of pregnancy, during which essential organs and structures begin to form.
3. Foetus
- From the 9th week until birth, the developing human is referred to as a foetus.
- During this period, the body continues to grow, and the organs mature, preparing the foetus for life outside the womb.
4. Baby
- After approximately 40 weeks of gestation, the baby is born.
- This marks the transition from an internal environment (womb) to an external one (outside world).
Conclusion
The sequence of development is straightforward and essential for understanding human growth. Each stage plays a critical role in the formation and maturation of the human body. The option 'A' accurately reflects this natural progression.
