Answer: (C)

The major event that occurred on September 11, 2001, was the coordinated terrorist attacks on the World Trade Center in New York City and the Pentagon in Arlington, Virginia. This day marked a significant and tragic moment in modern history as it led to the loss of nearly 3,000 lives and had profound effects on domestic and foreign policy in the United States and around the world. The attacks were carried out by the extremist group al-Qaeda, and they involved hijacked commercial airplanes that were used as weapons to target some of the most iconic and symbolically important sites in the U.S.

The aftermath of these attacks led to the initiation of the War on Terror, the implementation of increased security measures, and the establishment of the Department of Homeland Security in the U.S. Additionally, the events of September 11 drastically changed how countries approached terrorism and international relations, leading to military actions in Afghanistan.

Understanding this event is crucial as it has shaped contemporary global politics, security policies, and international relations for the past two decades.
