This ID the conclusion question presents a typical structure:
People say X, they're wrong, here's why. The "they're wrong" is the conclusion in this structure. (In this case, we get people say X, they're wrong, here's why, with an example of why)
(D) serves us a simple rewording of the "they're wrong.
(A) is the counter conclusion.
(B) is part of the premise example.
(C) is a paraphrasing of the premises.
(E) is part of the premise example.
As for the question:

We could say that the second sentence is supported by the ones that follow, however, that second sentence supports the second clause of the first sentence ("but that assumption is just not so.") So, even if it's an intermediate conclusion it's definitely not the main conclusion.
