The september 11th attacks were later linked to
a. hamas.
b. al-qaeda.
c. hezbollah.
d. saddam hussei

B. al-Qaeda 

The attacks were terrorist attacks linked to a group called al-qaeda. Hezbollah is an incorrect answer because he is the guy in Lebanon that has his own army. While Saddam was the iraqi guy who invaded Kuwait. 

The September 11th attacks were later linked to al-Qaeda.

September 11th, 2001 was a horrible day for the Americans and the whole United States, as al-Qaeda (Sunni Islamist organization) hijacked four airliners and crashed them into the World Trade Center in New York City. Two of the planes crashed into the World Trade Center, while one crashed into the Pentagon outside of Washington, D.C., and the last one failed, resulting in the airliner crashing into a field. Sadly, over 3,000 innocent people were killed that day. In 2004, the CIA tracked down Osama Bin Laden (one of the three leaders of al-Qaeda), and killed him. Abdullah Yusuf Azzam, the second of three leaders of al-Qaeda, died by a car bomb in 1989. The third leader of al-Qaeda remains alive till this day, and the US is giving $25 million to whoever gives information about his location.
