I believe the correct answer is D. Vagina

Explanation:

The female reproductive system is specially adapted to allow the natural process of birth to take place. It is open enough to allow sperms to be deposited and a baby to exit out the womb.

Further Explanation:a. Uterus

The uterus is what is commonly referred to as the womb. The top part has special smooth muscle called the endometrium which allows the zygote to be implanted and forms a placenta to supply the forming embryo with blood and nutrients that are needed. The smooth muscles also contract rhythmically when the baby is ready to be born due to action of the hormone oxytocin to push the baby out of the womb.

b. Cervix

This is also just a gateway to allow the baby to go out when required. It also contains a plug of mucus that when the egg is ready to be fertilized, the mucus becomes thin in consistency and allows sperms to pass through and fertilize the egg that is undergoing the ovulation phase in the menstrual cycle. After the egg has been fertilized, the mucus becomes thick again to block any more sperms and keep the internal environment of the uterus consistent for the baby to grow.

c. Fallopian tube

This is where fertilization takes place. After the egg has been released from the graafian follicle, it is pushed into the fallopian tube by fimbriae of the ovaries. If sperms are present, fertilization will take place and a zygote will be formed and will be implanted in the uterus.

d. Vagina

This is an muscular opening that allows for entrance and depositing of sperms during sexual intercourse. It has a specific pH to protect it and the other reproductive organs from pathogens and it also lubricates itself during sexual intercourse. Normal flora (friendly fungi and bacteria) live in the vagina that controls the numbers of other pathogens. This opening also allows a baby to pass out of the body during the process of birth.
