(A) increased by more than twice
(B) increased more than two times
looks like increased 3-4 times .
(C) more than doubled
(D) was more than doubled
looks like not only doubled , but something more happened to it .
(E) had more than doubled
Past perfect not appropriate here .

C it is !

Actually - they are all wrong! If it increased by twice (i.e. by 200%) then it tripled. C is correct grammatically if not mathematically.
