Which sentences? I don't understand
Out of all the pronouns, "whom" makes the most sense grammatically. This allows us to narrow it down to A or D.
In order for it to be the object of a preposition, there would have to be a preposition in front of it. "For," however is <em>not</em> a preposition. In fact, there isn't a preposition in the whole question.
This leaves us with option D, which is the correct answer.
You can better tell it's a direct object if you flip the sentence around a bit.
Your sister is waiting <em>for whom</em>?
"Whom" is essentially receiving the action. "Whom" is what your sister is waiting for.
Answer: D. whom; direct object.
In Shakespeare's Macbeth, the witches show Macbeth an apparition which tells him that he will not be defeated until Birnam Wood marches to Dunsinane. Macbeth, upon hearing this, feels relieved as he understands that it is impossible for the trees in the woods to march from one place to another. However, when Macduff and his army are coming to Dunsinane to fight Macbeth, they cut off branches from trees to hide behind them as they march towards Macbeth's castle. Because the army was hiding behind the branches, it looked like the trees were marching from Birnam to Dunsinane. In this manner, the prophecy was fulfilled.
The correct answer is the third one
