How were hijackers able to take over planes on september 11, 2001?

a. they attacked passengers.
b. they disguised themselves as pilots.
c. they attacked flight crews.
d. they set off bombs.

Technically, the answers are both A and C but more-so C.

Explanation:

This is because they also had to subdue passengers in order to successfully pull off any of the attacks. However, without subduing the crews, takeover of the planes would have been impossible. I'm gonna have to go with C in this instance, as takeover of the crew would have had higher priority amongst the al-Qaeda terrorists.
