The question address an argument between a physicist and a chemist. The physicist simply states that the requirements for low temperature nuclear fusion couldn't have been met by chemists, because their measurements and calculations are inaccurate. The chemist responds by mocking him and says he's simply jealous that chemists might have solved a problem that physicists couldn't solve.
The flaw of the chemist's argument is that he fails to address the claim proposed by the physicist; he simply avoids it altogether. This is seen in answer choice (D).
I confess I initially picked answer choice (B) while foolishly thinking that because the chemist failed to prove that perfect measurements are possible, he committed the largest flaw. Not so much! Perfect calculations are not addressed by the physicist who states that the opposing party's calculations are inaccurate. Does that mean they need to be perfect? No. Maybe nuclear fusion doesn't require them to be perfect. Regardless, the word "perfect" never comes into play in the argument.
