(C) is incorrect because it actually strengthens the conclusion. The conclusion is telling us that differences in the quality of care provided by hospital staff are probably responsible for differences in mortality rate, hence any answer choice that supports the fact that quality of care varies across hospitals varies would support the conclusion.

Let me know if this helps and if you have any further questions.
