Explanation: Assertion (A) is true because peacekeeping operations, as typically conducted by the United Nations, are designed to freeze hostilities by maintaining ceasefires and creating conditions for political dialogue, rather than directly resolving the underlying causes of conflict. Peacekeeping missions are usually aimed at maintaining peace and stability but do not address the root causes of the conflict themselves. Reason (R) is also true because peacekeeping is not explicitly mentioned in the U.N. Charter. While the Charter empowers the UN to take action to maintain international peace and security (under Chapter VI and Chapter VII), the concept of peacekeeping evolved over time as a practical solution to address conflicts. It falls somewhere between the peaceful settlement of disputes (Chapter VI) and enforcement action (Chapter VII), but it is not formally defined in the Charter. Thus, (R) correctly explains (A): peacekeeping focuses more on managing conflicts rather than solving them, and its evolution as a practice outside the formal provisions of the UN Charter aligns with this purpose.
