Answer:
The correct answer is B. The significance of the plane selections made by the terrorists on September 11 was that all four planes were traveling long distances, so they would have significant fuel on board to burn in the crashes.
Step-by-step explanation:
Four planes with 220 passengers were hijacked while flying to California from Boston International Airport, Washington Dulles International Airport and Newark Liberty International Airport. The four planes were destined for the state of California, the first three to Los Angeles and the last to San Francisco, so their fuel tanks were filled with about 91,000 liters (about 65,455 kg). The first two planes hit the Twin Towers of the World Trade Center, the third against the Pentagon, in Arlington County, near Washington D.C., and the fourth in the open field in Shanksville (Pennsylvania).
