Answer soon as possible would be appreciated The events taking place in two different locations are described below:

Location A: Movement of plates causes hot spots to move to a location with thinner crust
Location B: Tectonic plates move away from each other under the sea

In which location will active volcanoes most likely be formed and why?

Location A, because the magma breaks through the thin crust
Location A, because cracks between plates are filled with molten rocks which solidify
Location B, because the oceanic plate and continental plate are pushed up through the crust
Location B, because the thinner oceanic plate will be pushed under the continental plate
