The correct answer is:<br /><br />**B. Passengers launched a counter-assault on the cockpit so the hijacker/pilot crashed the aircraft.**<br /><br />### Explanation:<br />On September 11, 2001, United Airlines Flight 93 was one of four planes hijacked by terrorists. The intended target of Flight 93 is believed to have been either the U.S. Capitol or the White House. However, passengers aboard the flight, after learning about the other attacks that had occurred earlier in the day, organized a courageous counter-assault against the hijackers. During the struggle, the hijackers deliberately crashed the plane into a field near Shanksville, Pennsylvania, to prevent losing control of the aircraft to the passengers. This heroic act prevented further loss of life and damage at the intended target.
