When and where was the first meeting of the Security Council held?

The first meeting of the Security Council was indeed held on January 17, 1946, in Westminster, London. This gathering marked an important moment in the establishment of the United Nations and its framework for maintaining international peace and security following World War II.

London was chosen as the location for this initial meeting because it was one of the founding cities of the UN and a significant center of international diplomacy at the time. The meeting was a pivotal step in operationalizing the Security Council, providing a platform for member states to discuss issues of security and to create mechanisms for conflict resolution.

The other options do not accurately reflect the historical details of the Security Council's first meeting. For instance, the dates and locations specified in those choices do not align with the actual events surrounding the formation and initial deliberations of the Security Council.
