The correct answer is B. Debate
Step-by-step explanation:
A debate is a type of formal communicative situation in which two or more participants who have opposite arguments or positions towards a subject or situation that is commonly controversial, discuss and share viewpoints usually the purpose of showing one side has stronger argument than the other side and persuading the audience and others to believe and support one position. This differs from others such as persuasive speech because in persuasive speech there are no opposing sides and from position papers and editorials because these are written rather than oral. Therefore, the form of oral persuasion that features speakers on opposite sides of a controversial issue is a debate.
