The correct answer is C. The sources are in the incorrect order.
Step-by-step explanation:
The work cited page includes information about the sources used such as web pages, articles, books, etc. Additionally, the information included for each source depends on the type of source, and sources should be listed in alphabetical order.
In the cited page presented, the two sources include correct information because they follow the correct formatting for each type of source (a book and a webpage). However, the order of the sources is incorrect because according to alphabetical order Samson goes after Sallen, and not before it, considering the letter "l" is first that the letter "m" in the alphabet.
