60. 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.

请问这道题为什么选A（OG逻辑大全上的答案）

题干中最后一句话中scientists believe that most resistant bacteria in people derive from human consumption of bacterially infected meat.这个被细菌感染的肉，是否并未提示是被抗药性细菌感染的肉，如果是这样的话，A选项的结论如何提出来？如何信服？我觉得选A的逻辑并不严谨，盼大家能与我一起分析，谢谢！
