Where do subduction zones often occur?

a.
where a continental plate is being split into two parts

b.
where an oceanic plate is moving toward a continental plate

c.
where two oceanic plates are moving away from each other

d.
where two continental plates are colliding

A subduction zone is a region of the Earth's crust where tectonic plates meet. Tectonic plates are massive pieces of the Earth's crust that interact with each other. So, the best option is D) where two continental plates are colliding.

The answer is c) people evacuated but almost all returned
