In my opinion, it is logos. I think that the sentence is LOGICAL.
Let this be so.
His means of death, his obscure burial—
No trophy, sword, nor hatchment o'er his bones,
No noble rite nor formal ostentation,

D. The conversation you write must sound natural for the characters.
This answer is correct because conversation between characters can add humor. However, if the dialogue does not match the characters' personalities it will seem contrived and unnatural. This will lead to the characters being unreliable and take away from the overall writing. Some of the other statements could be considered correct as well in certain situations; however, they are not correct in all situations where as D is correct in all.
Stage directions are small lines put into the script (often in italics) that give the reader an idea of potential movement, what's going on in the scene, what other characters may be experiencing or the expression one may see on their faces. That would mean C is the best possible answer here.
