Answer:
O Appears to Gertrude in her chambers.
Step-by-step explanation:
William Shakespeare’s play "Hamlet" revolves around the revenge plan of a young prince Hamlet and his desire to avenge the wrongful death of his father, the King. The play deals with themes of loyalty, family, power, love, gender, etc.
The ghost was King Hamlet and he first appeared to the soldiers Bernardo and Marcellus, and then to Hamlet's friend Horatio. He also revealed to his son Prince Hamlet, how his own brother and Hamlet's uncle Claudius murdered him. He then wants his son to take revenge for his murder, which furthers the plot.
But the ghost did not appear to his wife, Prince Hamlet's mother, and King Claudius' new wife Gertrude.
Thus, the correct answer is the second option.
