Two tectonic plates move toward each other at boundaries

Divergent- this is when two tetonic plates move away from eachother,an easy way to remember it is like the two plates are dividing. 
Convergent- this is when two plates move together towards each other, remember this as collide
Transform- this is when the two plates rub against one another while sliding past, remember this by imagining how you'd split a paper in half from longways

the answer you're looking for is Convergent.hope this helps.

Its either c or d. i would go with d though, because im not sure if its legal in all of the us
