To be a good prince you have to put your people before anything
The correct answer is A. dialogue is used.
This is not a difference between literary and dramatic works. Dialogues are used both in literary texts and in plays, so they are not something that distinguishes the two genres. On the other hand, stage directions are written only in dramatic works, and only they are meant to be performed on stage, whereas novels and other literary works are not.
The correct answer to the question above is (b.) death. In Morte d'Arthur, the black hoods worn by the ladies who come to take King Arthur away on the barge are used to symbolize death.
