Answer: (C)

Verified step by step guidance

1. Understand the anatomy of the uterine tube (also called the fallopian tube). It consists of four main parts: fimbriae, infundibulum, ampulla, and isthmus. Each part has a specific function in the process of capturing and transporting the oocyte.
2. Learn the role of the fimbriae. These finger-like projections are located at the end of the uterine tube and are responsible for sweeping the ovulated oocyte toward the infundibulum.
3. Examine the infundibulum. This funnel-shaped structure is directly connected to the fimbriae and serves as the entry point for the oocyte into the uterine tube. It plays a critical role in capturing the oocyte after ovulation.
4. Understand the ampulla. This is the widest and longest part of the uterine tube, where fertilization typically occurs. However, it is not directly involved in capturing the oocyte.
5. Learn about the isthmus. This narrow portion of the uterine tube connects the ampulla to the uterus. It is primarily involved in transporting the fertilized egg to the uterus, not capturing the oocyte.
