Answer:
D. Fix the capitalization of the title of the play: In Act 4 of Arthur Miller’s The Crucible, Reverend Hale pleads desperately with Elizabeth Proctor in an attempt to convince her to save her husband's life by getting him to falsely confess to his accused crimes.
Explanation:
When you cite a work like a play or book, it needs to be capitalized. D does this correctly.
Why not B: "desperately" is the correct spelling.
Why not C: Splitting it into these two sentences would make the second sentence a fragment.
