Very clever argument. We're told that we have two groups of patients, 43 to each group. Everyone's got the same illness and receiving the same treatment. The ONLY difference is that one group is the kumbaya group. You know, we want to test the effectiveness (if it exists) of kumbaya so we isolate it. Okay, so... this is exciting what are the results? Well, the next premise tells us that after 200 years, everyone's dead. Therefore (the conclusion says), kumbaya does nothing.

See how ridiculous that argument is? I know I said 200 years whereas the actual premise said 10 years. But, 10 could also be just as ridiculous depending on what assumptions we entertain. How old are the patients? If they're 20 years old, then okay, fine, 10 years is whatever. If they're 100 years old already, then a 10 years later result is ridiculous to report. Of course everyone's dead.

That's precisely the subtly that (C) calls out. (C) says "Look, you should have reported on the results 8 years after, not 10. If you reported 8 years later, then most of the kumbaya group would be alive, while most of the non-kumbaya group would be dead."

(A) is tempting and it certainly doesn't help the argument, but it's a big stretch to say that it hurts the argument. First, we're left with just 4 data points of the original 86. It would be overgeneralizing to say something about the 86 sample from the 4 data points. Second, consider just the data points themselves. All we're told is that the kumbaya 2 lived longer than the non-kumaya 2. Okay, how much longer? 5 years? That'd be nice. Or just 5 seconds? That'd be useless.
