Best Answer Explained in Below-:

The term "round table conference" refers to a discussion format where participants, often from diverse backgrounds or organizations, gather to engage in dialogue on a specific topic. Characterized by its non-hierarchical setup, where all participants are considered equal, this format fosters open communication and collaboration.

Option C, "political or other discussion," accurately encapsulates the essence of a round table conference. Such gatherings often focus on critical issues, including political matters, social challenges, and policy development. By promoting an inclusive environment, round table conferences allow for varied perspectives, thereby enhancing the depth and quality of the discussion.

While option A ("big public meeting") suggests a larger assembly, it lacks the intimacy and focused dialogue inherent in round table discussions. Option B ("well-attended seminar") implies a more formal presentation format rather than open exchange. Lastly, option D ("debating competition") denotes a competitive atmosphere, which contradicts the collaborative aim of round tables. Therefore, option C best represents the fundamental nature and purpose of a round table conference, making it the correct choice.
