What new evidence was able to revive Wegener's theory

a) mid-ocean ridges exist, suggesting that parts of the ocean floor used to be above sea level

b) some parts of the ocean floor were younger than others, suggesting that some plates were being subducted

c) the coastlines of South America and Africa were simular in shape, suggesting that they shared a common tectonic plate

d) the mantel moves through convection, suggesting that rock in the Earth is not solid
