What would be the best option?
-I really enjoy stories that are ...... in the distant future.


And which do you think is the best option?
Students: We have free audio pronunciation exercises.
I really don't know but I'll go for "c".
I would definitely choose 'b'.
Thank you.
Students: Are you brave enough to let our tutors analyse your pronunciation?

In this case, set would be the word that you would use. Placed pretty much means the same thing and most of the time you can use either of them. When it comes to stories, though, the word "set" is used more often. You could use the word "placed" when you're talking about stories, but a better choice may be the phrase, "take(s) place." So your sentence would be: "I really enjoy stories that take place in the distant future."
