The Correct Option is B

Solution and Explanation

The fallopian tube is divided into three regions - infundibulum, ampulla and isthmus. The funnel-shaped region of fallopian which is closer to the ovary is called the infundibulum. The region of the fallopian tube which is closer to the uterus is called the isthmus. The region between the infundibulum and isthmus is called the ampulla. The ovum moves from the infundibulum to the isthmus through the ampullary region. Therefore, if the ampulla is blocked, the ovum cannot move from infundibulum to isthmus.

Female Reproductive System

The female reproductive system provides various functions. The ovaries produce the egg cells known as the ova or oocytes. The oocytes are then taken to the fallopian tube where fertilization by a sperm may occur. The fertilized egg is then transferred to the uterus, where the uterine lining has thickened in regard to the normal hormones of the reproductive cycle. Once in the uterus, the fertilized egg can implant into the thickened uterine lining and continues to develop. If implantation does not take place, the uterine lining is shed as menstrual flow. In addition, the female reproductive system produces female sex hormones that preserve the reproductive cycle.

During menopause, the female reproductive system slowly stops making the female hormones that are required for the reproductive cycle work. At this stage, menstrual cycles can become irregular and finally stops. One year after menstrual cycles pause, the woman is deemed to be menopausal.
