Plagiarism
is often times described as letter D: Both b & c - literary theft and cheating.
Because
in plagiarism, you copy the either word by word and the thought of the article without
referencing the original author and publish it as your own. In this essence,
you are not respecting the author of the article and his intellectual
expression. This is not an honest mistake because an honest mistake is
something not done on purpose while plagiarism is done on purpose.
