The statement above is correct. The references at the end of your paper should appear in alphabetical order by authors’ surname or by title (if there is no author), regardless of type of reference (book, film journal article, website, etc.).
Explanation:
The reference part is the cited list of work in any paper format. It includes the detailed information about the elements we cited in our main paper section.
It must beat the end of paper and strictly kept in the alphabetical order.
The reference shouldn't be attached into subheading, it must be separated by new heading at the end.
The reference part must be well organized and only those reference can be attached that is cited in the main paper.
I feel like it could be either A or B but im not sure due to the fact that I have no idea what the passage was about and which president we are discussing
