Sagot :

B. A dog walks to a stream and drinks when it gets thirsty
Why? A structural adaptation shows a being physically evolving in order to increase said being's chances of survival. B is not an example of this, since there is no mention of the dog's body changing  in order to increase the dog's chances of survival.  
(B) A dog walks to a stream and drinks when it gets thirsty.
