Which answer choice gives the BEST definition for the underlined word in the following sentence?
Based on the student's florid complexion, Vivienne knew that his nerves were getting the better of him before the debate.

If the student's nerves are getting the better of him, it is likely that he is either very pale or very flushed. Because "flushed" is one of the options, it is the correct choice. A complexion cannot be rambling. "Unclear" has a hint of promise, but it makes the stench more confusing, so it too is incorrect. It is difficult to known what is meant by the phrase "weak complexion," so answer choice "weak" is too unclear to be correct.
