To be honest, it's a little confusing myself, hehehe. But I believe that C might be the right answer or B. You might have to wait for other answers besides mine.
The answer is A). The excerpt "Alan Moore claimed that he was giving up writing for comics because he had been converted to religion of a serpent god called Glycon" is an example of plagiarism.
This excerpt from a student essay presents the same information that provides the book<em> Off to See the Wizard: A Biography of Alan Moore </em>by Jonah Sinnott. Furthermore, the author of this excerpt does not quote Sinnott nor adds the page number of his book. That is to say, the author takes Sinott's words and presents it as if they were his/her own words. In order to give credit to the real author, the writer of the excerpt should have named the source or added the page number as it has been done in the excerpts from options B), C) and D).
I believe B. is the answer
hope this helped
Could u be more elaborate on the question
The best answer among the following choices would be the third option C).
