Thanks for the forum love!
Now please repeat after me:

All right. You with me? Great.
This argument concludes that police presence doesn't decrease crime, on the basis that the most-patrolled neighborhoods have the most crime. But what if it's the crime rates that motivates the increased police presence? Maybe the crime rates would be even higher if there weren't so many cops on the beat. The argument assumes that this isn't the case.
(D) is correct because it identifies this oversight.
(C) is incorrect because there is absolutely no indication that the data sample is too small. In fact, the argument says that "the statistical evidence overwhelmingly supports the claim that such neighborhoods have the most crime." That's about the furthest thing from having too small a sample size.
Does that make sense?
