A) would not be effective

B) sounds like the answer, cause the association probably already did this survey already

C) 10 cats at a local shelter is not very many and too local

D) this would be a good choice, but why would a potential buyer spend money and time to do this?


Logically B is the right answer, but D would be the best if the potenial buyer had all the money and time.
