Question

which boundary type is responsible for the himalayas?

Explanation:

The Himalayas were formed due to the collision of the Indian and Eurasian tectonic plates. Convergent boundaries are where two tectonic plates move towards each other. In the case of continental - continental convergence (which formed the Himalayas), the two continental plates collide, and since both are relatively buoyant, they crumple and fold upwards to form mountain ranges.

Answer:

Convergent boundary (specifically continental - continental convergent boundary)
