Final answer:
Fair use allows copying and use of copyrighted material for several purposes, except for commercial exploitation.
Step-by-step explanation:
Fair use allows for the copying and use of copyrighted material for several purposes, but c) Commercial exploitation is not included.
Fair use encompasses activities such as criticism and commentary, teaching and education, news reporting and research. For example, a movie review that includes clips from the film would fall under fair use for criticism and commentary purposes.
However, using copyrighted material for commercial purposes, such as selling copies of a book without permission from the copyright holder, would not be considered fair use.
