Answer:
Option (3)
Step-by-step explanation:
The convergence of two plates leads to the formation of volcanoes. These volcanoes are formed on the over-riding plate, and are very intense and also the nature and the type of volcano also depend upon the composition of the magma, whether the silica composition is less or more.
But in comparison to the volcanoes that are formed in the divergent plate boundary, these are highly explosive due to the rapidly rising of magma towards the surface as the subducting plate melts, it exerts more pressure upward, thereby resulting in the releasing of pyroclastic materials, associated with smokes, ashes, and lava.
Thus, the most explosive volcanoes are formed in the convergent plate boundary.
Thus, the correct answer is option (3).
