How has Othello changed in Act IV? a. He is no longer in control. b. He trusts his wife more. c. He does not change. d. He has become more compassionate.

In Act IV of Shakespeare's "Othello," the protagonist, Othello, undergoes a significant transformation. Throughout the play, Othello is manipulated by Iago, who sows seeds of doubt and jealousy in his mind about his wife, Desdemona. By Act IV, Othello's trust in his wife has been completely eroded, and he becomes convinced of her infidelity without any substantial evidence. This manipulation leads to a loss of control and a drastic change in his character. He becomes irrational and violent, culminating in the tragic killing of Desdemona. Therefore, the correct answer is option (a) "He is no longer in control." Options (b), (c), and (d) do not accurately reflect Othello's character development in Act IV.
