According to the fair use doctrine

A) plagiarism is not an issue in the business world-it is a problem only in schools and academic circles.
B) crediting sources is all that is necessary to avoid legal problems.
C) once material is made public,it no longer belongs to the author.
D) you can use other people's work only if you don't prevent them from benefiting as a result.
E) any information found in two or more places is considered public.

The fair use doctrine allows for the use of copyrighted material for specific purposes, such as criticism, commentary, news reporting, teaching, scholarship, or research. However, the use must not prevent the copyright owner from benefiting economically from their work. Crediting sources may be a part of avoiding legal problems, but it is not the sole requirement of fair use. Plagiarism is always an issue, regardless of the context. Material that is made public still belongs to the author and is subject to copyright laws. Finally, the mere presence of information in multiple sources does not automatically make it public or free to use.
