A – Wrong
This statement is just blatantly denying the content of the text. We must find a flaw in the argument and not just deny it without evidence.
B – Wrong
The text focuses on whether machines wil gain consciousness or not. We have to find a flaw in the argument of machines gaining consciousness. We do not need to find a flaw in how long it will take.
C – Wrong
The text does not correlate science fiction with technological progress. It tries to put a valid explanation why such an event can occur.
D – Correct
The text makes claims which are slightly unrealistic and does so with lack of evidence. The concept of consciousness is still unclear in living organisms so the text cannot provide evidence of consciousness of the machines.
