Answer: Option (1)

Step-by-step explanation:

When an oceanic plate collides with a continental plate, the denser oceanic plate gets subducted beneath the less denser continental plate, and this down-going slab undergoes partial melting at greater depth known as the subduction zone, which forces the magma to rise up and form volcano on the over-riding plate.

These volcanoes are of three types, namely the composite, dome and shield volcano. For example, Mount Vesuvius and Mount Fuji.

Thus, the correct answer is option (1).
