Final answer:
False. Lady Macbeth is not killed despite being warned of treachery.
Step-by-step explanation:
False. Lady Macbeth is not killed despite being warned of treachery. In the play Macbeth by William Shakespeare, Lady Macbeth is a central character who assists her husband in his pursuit of power. She encourages Macbeth to commit murder to achieve his ambitions, but ultimately, it is Macbeth who carries out the deed and faces the consequences. Lady Macbeth dies offstage and her death is implied, but it is not directly shown or described in the play.
