Question

what is a state of work that becomes free for use 50 to 100 years after the authors death?

intellectual property
work for hire
public domain
derivative works

Explanation:

To solve this, we analyze each option:

• "Intellectual property" is a broad term for creations of the mind, not specifically about being free after author's death.
• "Work for hire" means the employer owns the work, not related to becoming free after death.
• "Public domain" refers to works not restricted by copyright, and many enter public domain 50 - 100 years after author's death (depending on jurisdiction).
• "Derivative works" are based on existing works, not about the state of being free after death.

Answer:

C. Public domain
