Answer:
Option (3)
Explanation:
The earth is comprised of a series of alternate basin and range at many places. These are formed due to the extensional force exerted on the crust from both the sides. Due to this, the crust gets stretched and under the influence of gravity, the heavy block moves downward relative to the other along the fault plane. This type of fault where one block (Hanging wall) goes down relative to the other (Footwall) is generally called a normal fault. The nearby block on the adjacent side remains stable and forms a hill. When this occurs in series, it results in the formation of basin and range.
Thus, it can be considered that the earth's basin and range topography is a result of vertical movement that arises along a fault plane.
Thus, the correct answer is option (3).
