a continental plate colliding with a continental plate an oceanic plate sliding past a continental plate a continental plate sliding past a continental plate an oceanic plate colliding into a continental plate
I gave my students this multiple choice question: Which of these tectonic plate boundaries is most likely to form a volcano?

Only one answer is correct among these 4 choices:
- a continental plate colliding with a continental plate
- an oceanic plate sliding past a continental plate
- a continental plate sliding past a continental plate
- an oceanic plate colliding into a continental plate

Could you tell me which one is correct?
