In which location would you find a passive continental margin?

Question

A near the Mariana Islands

B along the coast of Oregon and Washington

C along the west coast of South America

D along the east coast of the United States

Answer 1

D.  The others are all active plate margins with strike-slip faults and/or subduction zones.   The East Coast of the United States is NOT even close to be as "active" as the others.
