The right answer is: Fault block mountain with rough edges and steep cliffs

Explanation:

First you should know what faults are. They are just cracks in the Earth’s crust that allows the surface of the planet move along there and displace rock layers on either side as well. If there is any movement along the faults, earthquakes are likely to happen and with more time mountains can appear from under the intense pressure, as the Sierra Nevada ones. The presence of steep cliffs and jagged edges is a common characteristic of this kind of mountains.
