In which of the following does insemination occur in females?

During copulation (coitus) semen is released by the penis into the vagina.
This release of semen into the vagina is known as insemination.
The motile sperms swim rapidly, pass through the cervix, enter into the uterus and finally reach the junction of the isthmus and ampulla (ampullary-isthmic junction) of the fallopian tube where fertilization takes place.
