Final answer:
C. It foreshadows events that occur later in the story.
The excerpt from "Never Say Never" demonstrates foreshadowing in the plot, suggesting that Carlos's singing days might continue, which engages the reader and hints at future events.
Step-by-step explanation:
The excerpt from "Never Say Never" where Carlos is experiencing mixed emotions about his singing potentially being over indicates a significant contribution to the narrative's plot development. This moment is not the peak of the story's action, which would be the climax, nor is it the resolution where the conflict is settled. Instead, it is a key instance of foreshadowing, hinting to the reader that there might be more to come regarding Carlos's singing aspirations. In this context, foreshadowing is used to tease future events, engage the reader's curiosity, and add depth to the character's journey. Therefore, among the given options, the most accurate is C, as it foreshadows events that are likely to occur later in the story.
