I'm thinking D, because say the book "Night" it changes all the time, just like the character. As they move from concentration camp to concentration camp the character gets gloomier and more depressing and the camps are different every time. Hope this helped!
Suspenseful, it's that because the story has suspense in it.
Incorporate what? if you mean their selfs then i would say by giving a spice of them self or make their story have some character that relates to them, but then again the story itself is them already.
Following the victory at Troy, he and his men sail to Ismarus, the stronghold of the Cicones. With apparent ease, they sack the city, kill the men, enslave the women, and enjoy a rich haul of plunder. Odysseus advises his men to leave immediately with their riches, but they ignore his warnings.
Hope this helps :)
