The correct option is D Conciliation, mediation, and negotiation are more effective forms of preventive diplomacy.
Addressing the root causes and drivers of conflict is a long-term and complex task. Conflicts have multiple drivers and do not stop at state borders. The consequences of armed conflicts go well beyond the burden of death and disability. It limits the provision of basic services, forcing migration flows, and exposing affected communities to risks of death and disease. The human, social, and economic costs of armed violence and conflict adversely affect countries and societies, possibly for decades. Thus, it is extremely important to prevent the escalation of conflicts through the establishment of durable peace. This can be achieved by addressing the root causes of violence through reconciliation, institution building, and political and economic transformation. Thus, negotiation and mediation are more effective in conflict resolution than the use of military force.
