A. The cause-and-effect text structure shows how getting a puppy helped the author adapt to life in a new place.
Explanation:
The text is organized in a cause and effect structure. First the text shows that the narrator won a dog because the family needed to move to another city. In this case, we already have the first example of cause and effect, the effect being the dog and the cause being the change.
In the second paragraph, we can see that the dog was what made the boy not feel alone and make friends in the new city. Showing once again the cause and effect structure.
