Final answer:
To indicate the end of a story in ASL, Pat can assume a neutral face and body posture.
Step-by-step explanation:
To indicate that the story has come to an end in ASL (American Sign Language), Pat can use a combination of body language and facial expressions. Rather than the options provided, a more appropriate way for Pat to indicate the end of the story would be by assuming a neutral face and body posture (c). This could include lowering their hands, relaxing their facial muscles, and returning to a neutral position. By doing so, Pat can convey that the story has concluded without the need for additional gestures or actions.
