two molecules or moieties combine to form one single molecule, together with the loss of a small molecule. When this small molecule is water, it is known as a dehydration reaction; other possible small molecules lost are hydrogen chloride, methanol, or acetic acid.

The correct answer is D.
It would eventually go extinct. If you put a shark in a fresh water pond and it can't adapt to fresh water it will die.
