The conclusion is that there is no reason why the work of scientists has to be officially confirmed - since poor scientific work will e exposed and rendered harmless by other scientists replicating the experiments. If we wish to weaken this argument, we need to find some flaw in this plan - some reason why confirmation by replication is not good enough to make sure that scientists do a good job, and official confirmation needs to be performed. A gives you that reason - in the time it takes for peer scientists to get around to replicate the experiment and expose the errors the original scientists had committed, their original publication is taken as science, and may cause harm. Therefore, it is necessary to confirm the work before it is published, to prevent poor science from harming others in the few years before it is challenged and removed. Answer is A.
