The correct option is C 3 only

Note:

Fold Mountains: Fold mountains are created where two or more of Earth’s tectonic plates are pushed together. At these colliding, compressing boundaries, rocks and debris are warped and folded into rocky outcrops, hills, mountains, and entire mountain ranges.

Block Mountains: The raising of a fault block leads to the formation of block mountains. Higher blocks are called horsts and troughs are known as grabens. When the surface is spread apart, it leads to tensional forces coming into place when these tension forces split apart; it causes the center block to drop down. An example of this is the Sierra Nevada Range in the United States.
