I believe none of these options are correct. However, if you had to choose one, I would pick A - <span>Nina slid into her seat just as the bell rang and tried to catch her breath.

C. It makes the skull sound like a toy ball, adding to the grandfathers casual view of the deaths caused by the battle.

D is not correct because he would have described much worse if he wanted to frighten the children
