How does a well-developed character arc influence a story?

A well-developed character arc significantly deepens the emotional connection with readers by showcasing the transformation and growth of a character throughout the story. When readers witness a character experiencing challenges, making choices, and ultimately evolving—whether positively or negatively—they become more invested in the character's journey. This emotional engagement allows readers to empathize with the character's struggles, aspirations, and triumphs, making the narrative more impactful and relatable. Such connections are essential for a compelling story, as they enhance the overall reading experience and draw readers into the world crafted by the author.

The other options do not capture the core function of a character arc in a way that enhances the story's emotional depth. While comic relief can serve its own purpose, it does not directly pertain to character development. Predictable outcomes and multiple storylines may distract from a focused character journey rather than enrich the emotional landscape of the narrative.
