Personally opinion and reason for eliminating ans A is that it asks you the questions "introduce" which one of the following, so the question is "why physicians resist the new meaning", then the reasonable ans for this question should be "trade" is not a proper word for practicing medicine, why? because from etymology point of view, knowledge and "something else", which in conclusion, should be ans C "nature of the practice of medicine".
In general, the whole passage is trying to answer that question, so question 24 is actually sort of asking the purpose of this passage.
Hope this makes sense.
