Interviewer: A certain company released a model of computer whose microprocessor design was flawed, making that computer liable to process information incorrectly. How did this happen?

Industry spokesperson: Given the huge number of circuits in the microprocessor of any modern computer, not every circuit can be manually checked before a computer model that contains the microprocessor is released.

Interviewer: Then what guarantee do we have that new microprocessors will not be similarly flawed?

Industry spokesperson: There is no chance of further microprocessor design flaws, since all microprocessors are now entirely computer- designed.

The industry spokesperson’s argument is most vulnerable to criticism on the grounds that it

(A) presumes, without providing justification, that the microprocessor quality-control procedures of the company mentioned are not representative of those followed throughout the industry
(B) ignores the possibility that a microprocessor can have a flaw other than a design flaw
(C) overlooks the possibility that a new computer model is liable to malfunction for reasons other than a microprocessor flaw
(D) treats a single instance of a microprocessor design flaw as evidence that there will be many such flaws
(E) takes for granted, despite evidence to the contrary, that some computers are not liable to error
