··The correct answer is:
(a) Gamete formation → Fertilization → Zygote → Embryo
1. Gamete formation: These are cells used during sexual production. The male gamete is sperm while the female gamete is the egg or ova
2. Fertilization: This is the process where the male and female gametes fuss to form a single cell called a zygote.
3. Zygote: Is the combination of the parent gene(male and female gene) formed during fertilization. It contains the necessary genetic information to form a new human being
4. Embryo: this is the early stage of development of the new individual
