The correct answer is A. a series of bills passed after 9/11 to increase security by permitting the government to monitor communications and access to financial and personal information of people living in the U.S.
After the events of 9/11, president Bush had to do something - this is when his administration created this Act in order to improve security within the US, as well as to prevent any terrorist attacks from happening again. This would be done through surveillance and access into personal information.
