The correct answer is: C) New mountains are created through tectonic and volcanic activity.
There are three ways in which mountains are formed, therefore there are three different types of mountains: volcanic, fold and block mountains. 
It is important to say that these always involve plate tectonics, were huge "compressional forces, isostatic uplift and igneous (magma) matter, forces surface rock upward". In this way a landform higer than the surroundings is created, that is to say: a mountain.
There is no way a mountain is created by one of the other options given.
