Answer:

None of the options is correct.

Explanation:

The volcanic eruptions of a continental volcanic arch will be composed, marjoritly, by andesitic lavas and pyroclastic materials. A continental volcanic arc occurs when a volcanic arc is established on a continental margin of an active zone, which occurs as a result of the collision between two tectonic plates that form a subduction zone, that is, a zone that allows one of the plates to protrude on top of the other, pushing it down.
