 b. a dog walks to a stream and drinks when it gets thirsty.

This sentence describes a behavioral adaptation, which is an action animals perform to survive in their habitats, like seeking water when thirsty. In contrast, structural adaptations are physical features of an organism like body parts or coloration that help the organism to survive better in its environment.
