Answer: C. John Proctor to Elizabeth as she was getting arrested.
By this point in the play, John Proctor has greatly repented of his affair with Abigail. Moreover, he wants to regain the love that his wife and him once had for each other. He, therefore, promises to help Elizabeth and save her from the judgement of the town. He tells her:
<em>“I will bring you home, I will fall like an ocean on that court! Fear nothing, Elizabeth.”</em>
The expression means that Proctor will do anything he can to save his wife.
