Extrusive volcanoes are not found in which one of the following mountains?

Extrusive volcanoes are landforms created by the eruption of magma onto the Earth's surface. Most volcanic activity is concentrated along plate boundaries, particularly subduction zones. The Alaska region, including the Aleutian Arc, and the Andes Mountains are part of the 'Pacific Ring of Fire,' characterized by numerous active extrusive volcanoes formed by oceanic-continental subduction. The Rocky Mountains also contain volcanic features, such as those in the Cascade Range. In contrast, the Himalayas were formed by the continent-continent collision of the Indian and Eurasian plates. In such collisional zones, the crust is exceptionally thick, which prevents magma from reaching the surface to form extrusive volcanoes. Consequently, while the Himalayas are seismically active, they lack the active extrusive volcanism found in the other mountain ranges mentioned.
