Concept:Identify the other character on stage during Laertes' speech in the royal court scene.
Explanation:The extract is spoken by Laertes, who is asking King Claudius for permission to return to France.
This conversation takes place in Act 1, Scene 2, in the court at Elsinore.
Polonius is a member of the royal court and is present during this scene.
Rosencrantz and Guildenstern do not appear anywhere in this scene; they are introduced later in the play.
Ophelia is also absent from this particular court gathering.
Thus, among the listed characters, only Polonius is on stage while Laertes addresses the King.
Answer:D. Polonius
