The correct option is A uterus
In vitro fertilisation refers to a technique in which gametes (oocyte and sperms) are collected from either the parents or healthy donors or from any other source, and they are fertilised outside the body of the female, in almost similar conditions as that in the body. In this technique, fertilisation occurs outside the female body.
When the in vitro division of the zygote is continued further it forms the embryo with 16 blastomere morula, this embryo is then transferred into the uterus.
Fimbriae are the finger-like projections found at the terminal position of the fallopian tube which pick up oocyte released by the ovary. Transfer of embryo is not done to this part of the fallopian tube.
The developing embryo is not transferred to the cervix either. It is transferred to the uterus directly where it gets implanted.
