Where do most volcanoes form? A. Near plate boundaries
B. In the middle of tectonic plates
C. Where there is no plate movement
D. On a supercontinent​

Explanation:

Most volcanoes form at the boundaries of Earth's tectonic plates. These plates are huge slabs of the Earth's crust and upper mantle, which fit together like pieces of a puzzle. These plates are not fixed, but are constantly moving at a very slow rate. ... Sometimes, the plates collide with one another or move apart.
