The right answer is A.

For answer B it is rather the definition of a chemical structure, it refers to both its molecular topology, its geometry (molecular geometry or space group for a crystal) and its electronic structure.
The correct answer is fallopian tube.
The fallopian tube, also known as uterine tube or oviduct, carries the egg from ovary to the uterus.
The fallopian tube has finger-like projections or branches called fimbriae which reach out into the pelvic cavity and pick up an egg that has been released from the ovary.
The egg is tenderly brought into the fallopian tube where it begins to travel to the uterus.
The fallopian tube also serves as the location where fertilization of the egg by a sperm cell occurs.

B) Stasis occurs when the structure of a species in the fossil record does not change over a long period of time.

D) The adaptive radiation of mammals helps explain a rapid increase in mammal diversity of the fossil record after a mass extinction.
