Solution

The correct option is B blastocyst

After fertilisation, the zygote divides repeatedly to form a clump of many cells called blastocyst.

The blastocyst moves down the fallopian tube and finally gets embedded in the wall of the uterus.

After implantation, the blastocyst grows into an embryo which further develops into a foetus.
