单选题 The author mentions "sight unseen" primarily in order to emphasize that Shor's method

• (A) does not allow for the cloning of a bit of quantum information that has not first been recognized
• (B) tends to be less reliable than classical information correction, because it is impossible to discern whether Shor's is successful
• (C) has been accepted by physicists without much skeptical investigation
• (D) allows for a quantum correction where the individual states of quantum bits do not need to be reported.
• (E) quantum correction circuits tend to operate at random
