• A. a $\to$ c $\to$ d $\to$ a
• B. a $\to$ b $\to$ c $\to$ d
• C. c $\to$ a $\to$ b $\to$ d

Answer: (C)

c $\to$ a $\to$ b $\to$ d

1) Fertilization starts with the fusion of male gamete (sperm) and female gamete (zygote).
2) This fusion results in the formation of a zygote.
3) Zygote divided repeatedly to give rise ball of cells that forms embryo.
4) After the formation of embryo is gets embedded in the wall of uterus where it further forms the foetus so the correct order is in above steps.
