The andes, appalachian, and himalayan mountains all have something in common. they formed due to the
a. action of divergent plate boundaries.
b. action at transform plate boundaries.
c. action of convergent plate boundaries.
d. activity taking place at the boundaries of the ring of fire.

The one thing which Andes, Appalachian, and Himalayan Mountains have in common is they are all formed due to the action of convergent plate boundaries.

Option C

Explanation:

The Andes, Appalachian and Himalayas are all formed because of the movement of the convergent plate boundaries. Convergent boundaries are formed when two tectonic plates collide. The tectonic plates move towards each other and collide forming convergent boundaries.

These collision of the tectonic plates results in the plates to buckle into mountain ranges. At convergent boundaries, oceanic crust gets destroyed whereas the continental crust gets formed.
