C). It presents an alternative way for the author to show his thoughts.
Step-by-step explanation:
In reference to the book 'Travels with Charley,' the third statement correctly states that the author incorporates the conversations with the dog in the book to offer an alternative method to display his thoughts. The other perspective allows the readers to view the story from a different point of view and understand the key idea more effectively. It would also assist the readers in visualizing and relating to the story and evoke the desired response. Thus, option C is the correct answer.
