Which principal organ of the United Nations is primarily responsible for the maintenance of international peace and security and is the only UN body that can impose binding sanctions or authorize the use of force?

💡 Explanation:

The UN Security Council is the most powerful organ of the UN, responsible for maintaining global peace and security. Unlike the General Assembly, its decisions (resolutions) are legally binding on all member states, and it is the sole body authorized to mandate peacekeeping missions or impose mandatory sanctions.
