Answer:
C or choice 3.
Step-by-step explanation:
1 is subjective, as this is an opinion. 2 may be true however it is not backed up with any evidence and could be construed as an opinion. 4 is probably true but only the writer has that perspective about the dogs in their neighborhood.
3 had research statistics to show facts. It would be even clearer if the writer stated where the research came from.
