You are correct! A Works Cited list is a list of sources that you quoted in your research paper. It includes all the sources that you directly referenced or cited in your paper. These sources may consist of books, articles, websites, or any other materials that you used in your research and directly quoted from or paraphrased. The purpose of a Works Cited list is to provide readers with the necessary information to locate and verify the sources you used in your paper. So, in this case, answer choice A is the correct option.

So B?

The tutorial I posted states that works consulted as well as those quoted needs to be in the Works Cited List.

Both A and B are right. But check your text to be sure what that author says is correct.
