Solution

The correct option is C fimbriae
The fallopian tubes (oviducts) are accessory ducts in females. It consists of three regions : infundibulum, ampulla and isthmus.

The funnel-shaped part of each fallopian tube which is close to the ovary is called the infundibulum.

The finger-like projections present at the edges of the infundibulum are called fimbriae. The fimbriae collect the secondary oocyte (ovum) released from the ovary during ovulation. Hence option c is correct.

The infundibulum leads into a wider part, the ampulla.

The ampulla leads into a narrow, thick walled portion of the fallopian tube that joins the uterus known as the isthmus. Isthmus is the last part of the oviduct.

Cilia are small, slender, hair-like structures present lining the fallopian tubes. They help in the movement of gametes through the fallopian tube.

Uterine fundus is the dome shaped portion of the uterus which is superior to the fallopian tube.
