Since the routine use of antibiotics can give rise to resistant bacteria capable of surviving antibiotic environments, the presence of resistant bacteria in people could be due to the human use of prescription antibiotics. Some scientists, however, believe that most resistant bacteria in people derive from human consumption of bacterially infected meat.

Which of the following statements, if true, would most significantly strengthen the hypothesis of the scientists?

(A) Antibiotics are routinely included in livestock feed so that livestock producers can increase the rate of growth of their animals.
(B) Most people who develop food poisoning from bacterially infected meat are treated with prescription antibiotics.
(C) The incidence of resistant bacteria in people has tended to be much higher in urban areas than in rural areas where meat is of comparable quality.
(D) People who have never taken prescription antibiotics are those least likely to develop resistant bacteria.
(E) Livestock producers claim that resistant bacteria in animals cannot be transmitted to people through infected meat.

C,D and E can be dismissed right away. Between B and A, I go with A as it supports both the scientists view and the first hypothesis in the sentence

A it is.
Resistant bacteria develop through routine use of antibiotics.
Humans can develop resistant bacteria in 2 ways:
1. frequently using prescription antibiotics;
2. consuming products which already have resistant bacteria.
Animals can develop resistant bacteria only by consuming antibiotics on a regular basis, which they do if it's added to their feed.
