Answer:
Although Gertrude seems to be unaware of Claudius’s misdeeds at the beginning of the play, over the course of events, she starts doubting her assertions. Her beliefs are undermined when Hamlet murders Polonius and accuses his mother of betrayal. He reveals to her the truth about his father’s death and forces her to see her own villainy.
Answer:
B) Hamlet’s and Laertes’s accusations
Explanation:
Hamlet rants out at his mother when she asks him to stop going against the King (Claudius). In reply, he asks her that why had she betrayed his father and married his father's brother. Gertrude pleads Hamlet to stop speaking such things as she gets shattered on listening to the truth. She very well knows that Claudius has killed the King and had taken his place.
