Correct answer: "A plateau forms when a flat block of rock is uplifted, and a fault-block mountain does not."

Explanation: A plateau is a broad, relatively flat elevated area formed by uplift of large rock layers (or by lava flows). A fault-block mountain forms by movement along faults (usually normal faults from extension) that uplift and tilt discrete blocks of crust (horsts and tilted blocks). The other choices are incorrect: plateaus are not primarily caused by shearing, fault-block mountains form from normal (tensional) faulting not reverse faulting, and fault-block mountains involve fault-bounded uplift of blocks rather than uplift of a broad flat region.
