D. The Anti-Terrorism and Effective Death Penalty Act

is it A

Yes.

Yes, you are correct. The change in laws on investigating terrorism was primarily brought about by the USA PATRIOT Act, which is option A. The USA PATRIOT Act stands for Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act. It was passed by the U.S. Congress and signed into law by President George W. Bush in 2001, shortly after the 9/11 terrorist attacks. This act expanded the powers of law enforcement and intelligence agencies in their efforts to prevent and investigate acts of terrorism. It gave more authority to agencies such as the FBI and the NSA to collect information, conduct surveillance, and share intelligence in order to combat terrorism more effectively.
