Correct Response: A. The Digital Millennium Copyright Act (DMCA) prohibits circumventing encryption or other technology protecting digital works. The DMCA was designed to protect copyrighted material associated with digital technology. Therefore any software or other technologies that circumvent these protections is illegal. The law does not prevent the manufacture of file sharing software (B), or software that allows files to be downloaded (C). Software that allows digital material to be streamed over the Internet (D) is completely legal and not prohibited by the DMCA.
