The correct option is A Oviduct
Eggs or ova are the female gametes. They are formed in the primary sex organ i.e., ovary. From the ovary, they are taken up by the fimbriae of the fallopian tube which is also known as the oviduct. The fimbriae pass the egg to the isthmus of the fallopian tube through the ostium (aperture in the fallopian tube). So the correct answer is A.
