Final answer:
The statement that best develops the theme that people are not always what they appear to be is D) The narrator's inner thoughts and feelings contrast with their outward behavior, as it directly speaks to the duality of a character's presented self versus their true self.
Step-by-step explanation:
A theme in the story is that sometimes people are not always what they appear to be, and the statement that best develops this theme is D) The narrator's inner thoughts and feelings contrast with their outward behavior. This choice directly addresses the idea that there is a discrepancy between appearance and reality, a common narrative device used to explore the complexities of characters. It suggests an internal conflict within the narrator, highlighting the construction of 'masks' or facades that characters often present to the outside world.
The other options, while they could relate to themes of hidden depths or true intentions, are not as explicitly about characters presenting themselves differently than they are. For example, A) The protagonist finds a hidden talent in a seemingly ordinary character could point to underestimation rather than deceit, and C) The supporting characters show unexpected kindness to others may indicate complexity or change rather than a deliberate hiding of one's true self.
Overall, literature frequently examines the theme of appearances versus reality, and authors often use this to impart messages about understanding human behavior and society. This is but one aspect of theme, which is the central idea, message, or lesson in a story. Such themes can challenge readers to think deeply about the characters and conflicts presented in the narrative.
