Answer :
The sentence that is an example of third-person point of view is:
B. Their foolproof plan depended on my dog coming when Emma called him.
Explanation:
1. Third-person point of view is when the narrator is telling the story about other people (he, she, they) and not directly involved in the events.
2. In sentence B, the narrator is not directly involved in the action. Instead, they are describing how someone else's plan depended on the dog responding to a call.
3. The use of "their" and "my" in the sentence indicates that the narrator is observing and recounting the actions of others, making it an example of third-person point of view.
