a. there is no process that initiates destruction or formation of landforms in a transform boundary

hope it helps

correct me if I'm wrong

It’s D! Land formations cause linear valleys, small ponds, stream beds split in half, deep trenches, and scarps and ridges. The destructive grinding action between the plates at a transform plate boundary results in shallow earthquakes, large lateral displacement of rock, and a broad zone of crustal deformation. So it is not true that that there is no land formation or destruction in a transform boundary. Hope that helps!
