Answer: Continental/Continental (C)
Explanation: "Convergent boundaries occur between tectonic plates that are colliding or running into each other. There are three types of convergent boundaries. They differ in which types of crust are colliding. The first type of convergent boundary involves a collision between two continental plates. When two continental plates collide, they buckle under pressure and push the continental crust upward. The collision between continental plates produces non-volcanic mountain ranges. For example, The Himalayan Mountains were formed in this manner".
