The right option is; normal faults
A graben is found between two normal faults.
A graben is a region of land that is positioned between two normal faults and it is a depression in land elevation as the land masses on each side separate. A graben occurs in a fault zone as a result of geological forces that cause the land between faults to be displaced downward. Graben usually occur along side with horsts. Examples of graben landforms include; East African Rift Valley in Africa, Viking Graben in Europe and Santa Clara Valley, in North America
