The correct option is D Fallopian tube
The Fallopian tubes, also known as oviducts and uterine tubes are two very fine tubes lined with ciliated epithelium, leading from the ovaries of female mammals into the uterus. When secondary oocyte escapes, it is caused by fimbriated end travels to the ampulla of the uterine tube, where typically the sperm are met and fertilization occurs; meiosis II is promptly completed. After Fertilization, zygote is formed. Hence, option B is correct.
