To conduct oneself in a proper manner. Usually refers to debate, as in _______ in debate.

• A. Deliberation
• B. Debate
• C. Decorum
• D. Decorum in debate

Answer: (C)

Decorum means proper conduct, civility, and good manners. In debate, it governs how participants interact—speaking respectfully, avoiding interruptions, addressing the chair properly, and following the rules of courtesy. That matches the clue about conduct in debate, so it’s the best choice. Deliberation is about careful thinking, not behavior; debate is the act of arguing itself; and while decorum in debate is a valid phrase, the term that names the quality described is decorum.
