Final answer:
The bills of attainder from the provided options are a law that says the Klu Klux Klan is guilty of harassment' (a) and 'a law that says a Communist cannot be a member of Congress (c). Both options designate guilt or impose punishment without a judicial process, which is characteristic of a bill of attainder.
Step-by-step explanation:
In the context of the rights of the accused and the prohibition of bills of attainder, which are laws that impose guilt and punishment on individuals or groups without a trial, we can identify the relevant options from the question presented.
- a. a law that says the Klu Klux Klan is guilty of harassment qualifies as a bill of attainder because it designates a specific group as guilty without a trial.
- c. a law that says a Communist cannot be a member of Congress is also a bill of attainder as it imposes a punishment on a specific group without a judicial proceeding.
Options b and d do not qualify as bills of attainder as they regulate general behavior and do not impose guilt or punishment without a trial.
