According to the principles of deindividuation, the best strategy to disband an angry mob of protesters is option C: using a loudspeaker, address several questions to a specific individual in the crowd. By addressing specific individuals, the police officer can potentially disrupt the anonymity and diffusion of responsibility within the group. This approach may prompt individuals to re-engage their personal identity, making them less likely to engage in destructive or violent behavior and facilitating a more rational and controlled response from the crowd. Option A, encouraging calm through a loudspeaker, could also be effective in promoting a collective sense of responsibility and reducing deindividuation. Options B and D, involving the use of force or threats, are more likely to escalate tension and aggression, potentially exacerbating the situation.
