It looks like you're misreading what (C) is saying: if all dishonest people are rich farmers (H Rf), then we know that if you're not a rich farmer, you're honest (Rf H), but it still leaves open the possibility that some rich farmers are honest. (C) only gives us information about the "dishonest" group, not the "rich farmer group".
(A) works because its contrapositive, Pf Hf, when translated from "not poor" to "rich" and "not honest" to "dishonest," becomes Rich Farmers Dishonest Farmers, which is exactly what the conclusion states.
Hope this helps!
