Answer:

E. The ancestral reptiles could not have survived long at sea.  

Explanation:

To get the answer to this question, the key is to focus on which option strengthens the conclusion of the scientists.

The scientists concluded that the sea level rise left at least a part of the Islands unsubmerged which may have caused some of the reptiles to survive. looking at the options, Option A weakens the conclusion of the scientist because if they can adapt, more of the reptiles would have survived in all the islands.

But option E strengthens the conclusion because since the ancestral reptiles could not survive long at sea, it therefore implies that there was at least a part of the island that was not submerged which helped in the survival of a population of the ancestral reptiles during the sea level rise.

Option B is irrelevant and option C is wrong because the statements clearly indicates that fossils shows that the current reptiles  can be traced to the ancestral reptiles on the Island.
