The correct answer is C) They demanded that the US withdraw its forces.
The other options of the question were A) They joined forces with the Saudi government. B) They asked for US support to take over Saudi Arabia. D) They asked for US support to help take over Iraq
Some Islamic groups responded to the presence of US troops in Saudi Arabia before September 11, 2001, in that "They demanded that the US withdraw its forces."
However, everything changed after the terrorist attacks of September 11, 2001. The Bush Administration had to make tough decisions to counter-attack the aggression and decided to attack Afghanistan to punish terrorist cell al Qaeda and its leader, Osama Bin Laden. George Bush also decided to create the Homeland Security Department, to protect the American people.
