O It signals a similarity between alligators andcrocodiles.

Answer:

The answer is B, it signals a difference between alligators  

Explanation:

If you use while in a sentence comparing two things as a conjunction...it's meaning changes to show the contrast between the two ideas.  

Ex: Crocodiles have long, pointed snouts WHILE alligators have wider and rounder snouts.  

In this case While is highlighting the difference between the two animals.
