What is the significance of rebuttals in a debate?

Rebuttals play a crucial role in a debate as they allow participants to directly confront and address counter-claims made by the opposing side. By providing evidence and reasoning that refutes opposing arguments, rebuttals help clarify one's own position and strengthen the overall case being presented. This interaction not only enhances the validity of the debater’s arguments but also demonstrates critical thinking and the ability to engage with opposing viewpoints. Effective rebuttals can influence the audience's perception and understanding of the issue, making them a fundamental component of persuasive debating. This opportunity to engage with counter-arguments is what makes option C the correct choice.
