Which combined intervention best synthesizes crowd classification knowledge and evidence-based strategies to reduce violent escalation at a planned, high-tension rally?

• A. Increase visible militarized police tactics, use crowd dispersion techniques that maximize fear, and reduce communication channels between organizers and officials so that participants cannot coordinate nonviolent alternatives.
• B. Ban all public gatherings and immediately arrest anyone who attempts to assemble, because suppression by force universally eliminates any risk of escalation without secondary social consequences.
• C. Establish designated dialogue zones to channel acting-crowd goals into negotiation, deploy de-escalation-trained liaisons between organizers and police, and create clear nonviolent norms reinforced by community leaders prior to the event.
• D. Do nothing and presume spontaneous crowd dynamics will always resolve conflicts internally without influence from organizers, police, or community actors.
