Answer:
The correct answer is letter "D": extended the time for the federal copyright protection to 70 years beyond the life of the creator/author.
Explanation:
The Sonny Bono Copyright Extension Act mostly known as the Copyright Term Extension Act (CTEA) is a regulation passed in 1998 to extend the length of copyrights. It is an amendment to the Copyright Act of 1976 where copyrights granted exclusiveness over inventions for 50 years after the decease of the author if individual or 75 years for corporate creations.
With the CTEA copyrights are granted to be used by individual creators only for until 70 years after their decease or 120 years for corporate authorship.
