What is the main reason the United States removed the Taliban from power shortly after the September 11, 2001, attacks?

Al-Qaeda, led by Osama bin Laden, planned the September 11 attacks, and its leaders were based in Afghanistan under Taliban rule. The Taliban allowed al-Qaeda to operate there and refused U.S. demands to hand over its leaders, so the United States invaded Afghanistan and removed the Taliban from power. The correct choice is “The Taliban allowed al-Qaeda to use its country as a base.”
