i so want to select D - but i know it is blatantly wrong...

Will pick C - though dont have a good reason.

E and B are in same lines, so choosing one of them seems wrong to me.

C)...

If A, then B.
If B, then C.
If C, then D.

if it rains(A) i take my umbrella(B).
if i take my umbrella(B) i will wear my hat(C).
if i wear my hat(C) i will go and drink a coffee(D).

(A) If D, then A. => i drink coffee when it rains as well when the sun shines and for many other reasons => wrong
(B) If not B, then not C. => when i don`t take my umbrella i will wear my hat anyway => wrong
(C) If not D, then not A. => A is a condition for B; B is a condition for C; C is a condition for D. i don`t drink a coffee, so the preceeding conditions did not happen. => right
(D) If D, then E. => nothing about E => wrong
(E) If not A, then not D. => i drink my coffee anyway. maybe it rains, mabye it isn`t raining. => wrong

it should be B because C is a necessary condition for B, abd if there is no B then there is no C

If B, then C.

(B) if not B, then not C.

Let's exemplify it.

if it rains, I'll take an umbrella.
can it prove that if it doesn't rain, I do not take an umbrella.
I don't think so.

But we can say if I don't take an umbrella, then it must not rain.

So, I lean to C.

If A->B, B->C, C->D

(A) is out. We only know If A->B->C->D. So If A then D, not the other way roudn
(B) is out. We only know if !C, then !B.
(C) is the anwer. !D->!C->!B->!A so If !D then !A
(D) Can't link D to E
(E) From the logic in C, we know !A cannot be logically linked with !D

C it is.
