I got this one correct but to me C was also tempting. can someone explain why C is the wrong choice?

Hi,
C is wrong because

lets see the choice


(C) overlook the possibility that objections about safetyare not the only possible objectionsto the practice

and the conclusion


Supporters of food irradiation have cited this research as certain proof that food irradiation is a safe practice.

If you look at the conclusion the objections were related to SAFETY and the conclusion is also about SAFETY..
C talks of other objections but the argument deals with ONLY safety or SAFE practice....

A group of scientists who have done research on the health effects of food irradiation has discovered no evidence challenging its safety. Supporters of food irradiation have cited this research as certain proof that food irradiation is a safe practice.

A flaw in the reasoning of the supporters of food irradiation is that they

(A) assume that the scientists doing the research set out to prove that food irradiation is an unsafe practice

(B) are motivated by a biased interest in proving the practice to be safe

(C) overlook the possibility that objections about safety are not the only possible objections to the practice

(D) neglect to provide detailed information about the evidence used to support the conclusion

(E) use the lack of evidence contradicting a claim as conclusive evidence for that claim.

cracked this one in slightly more than 1 minute.
no evidence to challenge the safety ≠ safe

E - use of lack of evidence contradicting the claim that it is safe as the premise to support the conclusion that it is safe.

Why is A out of consideration? In A, if a research found by accident/ or generally that a practice is safe, then how can they cite it as evidence?

My thoughts on this -

The stimuli doesn't tell us anything about the scientists. So this is extra information. Moreover, the use of strong words such as 'as out to prove' made me rule out this option.

Experts please correct me if I am wrong

Conclusion:

Food irradiation is a safe practice.

This is still a safety claim, not a claim about ethics, cost, taste, legality, etc.

“Safe practice” here = safe to use, not “perfect in every way.”
