Final answer:
Iago reminds Othello of Desdemona's deception to further incite Othello's jealousy and manipulate him into doubting her fidelity.
Step-by-step explanation:
Iago reminds Othello that Desdemona deceived her own father because Iago's goal is to stir Othello's jealousy and doubt towards Desdemona. He suggests that if Desdemona can deceive her father, who trusted her, she is just as likely to deceive Othello, her husband. By doing this, Iago is manipulating Othello to suspect Desdemona of infidelity, thereby furthering his own malicious agenda.
Iago reminds Othello that Desdemona deceived her own father because Iago wants Othello to doubt Desdemona's trustworthiness. In William Shakespeare's play Othello, Iago manipulates Othello's perception of Desdemona in order to fuel Othello's jealousy and doubts about her fidelity.
