You have plagiarized if you have *

A. No page numbers where you found the facts, no quotation marks around quotes, no source credited with providing you with the information, and no work cited page.
B. Quotes around the author’s ideas, no in-text citation with the quote, and a work cited page.
C. Copied and pasted information from a website but listed the website on the works cited page
D. All of the above

I think it might be A or D, am I correct?

One of those is correct, not both.

Alright, would it be D?

Its A

No, I don't think so. B is confusing to me. Does it mean that the quotation IS in the works cited page, or not? In either case, it means the quotation is improperly cited. The quotation marks indicate the writer is not claiming the words to be his/her own. The same with C. It indicates improper citation, not plagiarism. Quotations must always be in quotation marks and properly cited.

The question was confusing me too. Thank you for the help!

Yes, you are correct. Option D, "All of the above," is the correct answer. If you have no page numbers, no quotation marks, no source credited, and no work cited page (Option A), then you have plagiarized. Similarly, if you put quotes around the author's ideas without proper in-text citation and only include a work cited page (Option B), that also constitutes plagiarism. Lastly, if you copy and paste information from a website, even if you list the website on the works cited page (Option C), it is still considered plagiarism unless proper citation and quotation methods are used.
