What describes the first nine months of human development in a correct order?

The first nine months of human development begin with fertilization, where a sperm cell merges with an egg to form a zygote. This zygote undergoes rapid cell division as it travels down the fallopian tube and implants itself into the uterine lining, becoming an embryo. Over the next several weeks, the embryo develops major organs and structures during the embryonic stage. By the end of the nine months, the fully developed fetus is ready for birth, having completed critical growth and maturation processes.
