C too.

If C then D is sure. If not D they there was no C. So accordingly, if not C then there was no B. and so on..........

(A) If D, then A: Maynot be true because D could have resulted not because of C but because of X or Y or Z.
(B) If not B, then not C: Also not true C could result because of K/L/M.
(C) If not D, then not A: Yes it is. If not D they there were no C. So accordingly, if not C then there were no B and so on..........
(D) If D, then E: nobody knows.
(E) If not A, then not D: Not true because other than A could cause B or C's occurance. If any thing other than A causes to occure B and the same applies to C, then D could result because not of A.
