Why the answer is B, and why the others tempt you.
The Great Rift Valley was formed through a process of faulting, where tensional forces caused sections of the earth's crust to subside (sink) between parallel fault lines, creating a long, narrow trough. This is a classic example of a rift valley or graben structure, not folding or erosion.
