Final Answer :
C
Explanation :
A human organism begins as a zygote, which is the initial cell formed when a sperm cell and an egg cell merge. The zygote then undergoes several stages of development, eventually becoming an embryo. The embryo continues to develop and after about eight weeks, it is referred to as a fetus until birth. Therefore, the correct sequence is from zygote to fetus.
