Solution

Old crust is destroyed at convergent boundaries, where tectonic plates move towards each other. This process is known as subduction, where one plate is forced under another and melts into the mantle.

Based on the information given, the two plate boundaries where old crust is being destroyed are:

(Choice A) the Cocos and Caribbean plate boundary (Choice D) the Nazca and South American plate boundary

This problem has been solved
