The correct option is A 10-12 cm, from periphery of each ovary to uterus
Females have two fallopian tubes, each fallopian tube is about 10-12 cm long and extends from the periphery of each ovary to the uterus.
Each fallopian tube consists of three regions: infundibulum, ampulla and isthmus.
The funnel shaped portion, which is close to the ovary, is called infundibulum.
Ampulla is the widest and the longest part of the fallopian tube. It is present in between the isthmus and infundibulum regions of the fallopian tube.
The isthmus is a narrow, thick walled portion of the fallopian tube that joins the uterus.
