Final answer:
The incorrect statement regarding Act IV of 'Othello' is that Emilia says Iago wrongfully accused her of having an affair with Othello.
Step-by-step explanation:
The statement that is NOT true based on the events of Act IV in Othello is: Emilia says that Iago wrongfully accused her of having an affair with Othello. This statement is incorrect because Emilia does not make such an accusation regarding herself and Othello. In Act IV, it is actually Desdemona who struggles with the false accusations against her. She expresses that she could never even say the word adulteress, let alone be one. Furthermore, Emilia does testify to Othello that Desdemona has never been alone with Cassio, thus trying to defend her lady's honor. Therefore, the correct answer is 2) Emilia says that Iago wrongfully accused her of having an affair with Othello
