Does stress build at fault lines affect Earth's rocks?

Forces may affect the Earth's rocks with stress at the faults, but I don't see stress building at fault-lines to be a direct cause of this. I'll cross this one out. Number one seems to be the correct answer as it makes the most sense in the context of the question as well as in its content.

What type of stress produces a fault?

Source: Cross section by José F. Vigil from This Dynamic Planet—a wall map produced jointly by the U.S. Geological Survey, the Smithsonian Institution, and the U.S. Naval Research Laboratory. In terms of faulting, compressive stress produces reverse faults, tensional stress produces normal faults, and shear stress produces transform faults.

How does stress affect the deformation of rocks?

At the Earth’s surface, rocks usually break quite quickly, but deeper in the crust, where temperatures and pressures are higher, rocks are more likely to deform plastically. Sudden stress, such as a hit with a hammer, is more likely to make a rock break. Stress applied over time often leads to plastic deformation.

What causes a fault to move?

This fault motion is caused by extensional forces and results in extension. [Other names: normal-slip fault, tensional fault or gravity fault] Examples include Basin & Range faults. Reverse fault— the block above the inclined fault moves up relative to the block below the fault.
