A thorough search of Edgar Allan Poe's correspondence has turned up no

A thorough search of Edgar Allan Poe's correspondence has turned up not a single letter in which he mentions his reputed morphine addiction. On the basis of this evidence it is safe to say that Poe's reputation for having been a morphine addict is undeserved and that reports of his supposed addiction are untrue.

Which of the following is assumed by the argument above?

(A) Reports claiming that Poe was addicted to morphine did not begin to circulate until after his death.
(B) None of the reports of Poe's supposed morphine addiction can be traced to individuals who actually knew Poe.
(C) Poe's income from writing would not have been sufficient to support a morphine addiction.
(D) Poe would have been unable to carry on an extensive correspondence while under the influence of morphine.
(E) Fear of the consequences would not have prevented Poe from indicating in his correspondence that he was addicted to morphine.
