Answer:
D.
Step-by-step explanation:
"The Jungle" is a novel written by Upton Sinclair. In his novel he shares about the unsanitary conditions of the meat industries and unethical practices adept by them to earn profit rather than thinking about the well-being and health conditions of the public.
The quote from the text that best supports the idea that a factory is likely to employ such questionable practices is in option D. The factory employed such unethical practices to earn money and profit at the risk of public health. The sausages that these industries sell come out of the same machinery, but sold with different stamp. The sausage bundles sold with the stamp 'special' have nothing special in reality, but just a way to earn extra money.
Therefore, option D is correct.
