(A)An adaptation is a characteristic that helps an animal survive in its habitat. All animals must be able to obtain food and water, protect themselves from harm, withstand the climate, and reproduce young so the species doesn't become extinct. ...

More fluid bilayers will be formed when the saturation of the fatty acids chains on a phospholipid is decreased.
Fatty acids are present in animals, plants and other microorganisms. They are composed of the carbon chain with carboxyl group at the end of the chain. The fatty acids are the vital components of the lipids, which are the essential fat soluble components. When the saturation level of these acids is decreased, it leads to the formation of more lipid bilayers.
Hence, the correct answer is 'more fluid bilayers'.
