Concept:Identifying the speaker who challenges the Ghost in Act 1 Scene 1 of
Hamlet.
Explanation:In this scene, the Ghost of King Hamlet appears before the guards and Horatio.
Horatio steps forward and boldly addresses the Ghost.
He pleads with it to speak, asking whether it knows about Denmark's fate or hidden treasure.
The lines describe a person directly questioning the Ghost, which matches Horatio's role.
Neither Hamlet nor Claudius is present at this moment in the scene.
Mercellus is a guard who watches but does not speak these exact lines.
Therefore, the speaker is Horatio.
Answer:C. Horatio
