at which point is crust neither created nor destroyed?\n island chain\n mid - ocean ridge\n divergent…

Brief Explanations:

At a transform - boundary, tectonic plates slide past each other horizontally. There is no creation of new crust as in mid - ocean ridges (divergent boundaries) where magma rises to form new crust, nor is there destruction of crust as in subduction zones associated with convergent boundaries. Island chains are often formed due to volcanic activity related to plate tectonics but are not points where crust creation and destruction are balanced.

Answer:

transform boundary
