Answer: Option (1)
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.
