Which of the following is not considered evidence that supports the theory of plate tectonics?
a) coastline similarities
b)rock patterns
c) vegetation

Option C, vegetation

Explanation:

The coastal characteristics are depended on the plate tectonic settings. A collisional coast is formed when coast of tectonic setting collide with the crustal bedrock thereby causing slow uplift. On the other side island arc coast is formed when there is collision between two oceanic crust plate edges.  

The rock pattern causes elevation differences between continental and oceanic crust.  

Vegetation type or pattern in no way supports the theory of plate tectonics and hence option C is correct.
