(A) has for centuries been slowly weaving its way through the roots of trees, to become

(B) has slowly woven its way through the roots of trees for centuries, and so becoming

(C) that has been slowly weaving its way through the roots of trees for centuries has become

(D) that has for centuries slowly woven its way through the roots of trees and has become

(E) that, having slowly woven its way through the roots of trees for centuries, to become
