Answer: The character who reports that Polyneices has been buried is A) Guard.
Explanation: In Sophocles' Antigone, the Guard is the first to inform Creon that someone has buried Polyneices and disobeyed the ruler's orders. However, in that precise moment, Creon does not know that the person that has gone against his authority is his son's fiancée and Polyneices' sister, Antigone. After taking Antigone to Creon, the Guard expresses that he feels pain for denouncing Antigone, whom he considers a friend. Moreover, he does not condemn Antigone for her actions.
