Based on this negation, can we say that Option C is not correct?
Negated C = "Some enterprises that do not use controlled experiments and statistical tests are genuine sciences."
Let's say there are 100 experiments in total, based on negated C, 75 perform controlled experiments and 25 don't. The conclusion is not destroyed due to 25 experiments, hence, Option C iswrong.

You cannot get the answer using negation here because this is not a necessary assumption question. It is a sufficient assumption question (the one that leads to theconclusion).
ThanksKarishmaB
I have a follow-up question, how can we recognize that it is not a necessary assumptionquestion?
Notice the question stem:
"The conclusion above is properly drawn if which of the following is assumed?"
You want the conclusion to be properly drawn i.e. the argument to become valid. You should be able to deduce the conclusion which means that the correct option should be sufficient
