Solution
The correct option is B Ampulla
Each fallopian tube is about 10-12 cm long and extends from the periphery of each ovary to the uterus, the part closer to the ovary is the funnel-shaped infundibulum. The edges of the infundibulum possess finger-like projections called fimbriae, which help in collection of the ovum after ovulation. The infundibulum leads to a wider part of the oviduct called ampulla in which generally male sperm and female ovum meet and fertilization occurs. Then narrow part of the oviduct, isthmus has a narrow lumen and it joins uterus via intramural part.
