If the central idea of the chapter is to be written in one sentence, which one will be most mature?

Correct answer: True devotion can change both a person's limitation and an instrument's cultural limit into respect

A mature central idea must synthesize the two parts accurately, show their common theme, and preserve their important difference. Evelyn’s story demonstrates that sincere training and determination can turn a physical limitation into confidence, independence, and artistic excellence. Bismillah Khan’s story shows that equally deep devotion can raise the cultural status of a traditional instrument and earn it lasting respect. Option B brings these strands together: the person’s limitation and the instrument’s social limitation are both transformed through practice and dedication. A reduces music to entertainment, C ignores effort and learning, and D presents disability and tradition negatively, contrary to the chapter’s message.
