Final answer:
A freelance writer is usually paid a flat fee or honorarium for their work on a magazine article, not royalties which are common in book publishing.
Step-by-step explanation:
A flat fee is a fixed amount of money that the writer receives for their work, regardless of how many copies of the magazine are sold.
This is different from a royalty, which is a percentage of the revenue earned from the magazine sales, and an honorarium, which is a token payment made for a service rendered.
A freelance writer is often paid a flat fee for a magazine article. They may receive a set amount of money for their work regardless of the article's future performance or frequency of reprint. In some cases, they may also receive an honorarium, which is a payment given for professional services that are rendered nominally without charge. Royalties are typically not a form of payment for freelance writers as they are more common in book publishing where authors receive payments based on sales. Therefore, the answer is D, both B and C.
