The author wants the audience to feel sympathy for the Burmese people because he presents them in a negative light, leaving the viewer with a negative impression of them.
(D) They give a detailed breakdown of the figures for each type of infection used to compile the estimated totals of illnesses and deaths.
Looking through each of these options, D would not work because it does not mention the regulation industry. You could say the same for B as there is not enough information in the answer to support the question. Answer choice A doesn't seem to give as much factual information that pertains to both the pet food regulation industry and accuracy of information on labels as C does, so I would say C is the best answer here.
