Your question is incomplete because you have not provided the underlined portion, which is:
teeth. The reasons behind this dental decision remain unclear.
Answer:
C teeth, but the reasons behind this dental decision remain unclear.
Explanation:
The second clause must provide contrast because both sentences have opposing ideas, so to join them, it is proper to introduce opposition with a coordinating conjunction like but.
The rest of the alternatives are incorrect because A does not involve disparity, B introduces consequence instead of contrast, and D repeats the word archealogists, which is already mentioned in the first clause.
The choice that most adequately links the two sentences at the underlined part would be as follows:
C). teeth, but the reasons behind this dental decision remain unclear.
The given sentences can most efficiently be linked using the coordinating conjunction 'but.'
This helps in keeping both the ideas independent while stating the action in the first part and the cause in the latter part.
This helps in smoothly associating the two ideas while making it comprehensive.
Thus, option C is the correct answer.
