The great rift valley of East Africa is a notable example for the process of ________.
The East African Rift Valley, as the region is known, formed as the result of the faulting process where the Somalian and Nubian plates are pulling away from the Arabian Plate. The eastern branch of the rift passes through Ethiopia as well as Kenya. And its western branch forms a giant arc from Uganda to Malawi.
So the above information shows that the great rift valley of East Africa is a notable example for the process of faulting. Thus correct option is B. Other options are not suitable.
