Answer: Gertrude, Fortinbras
Explanation: Of the listed characters, just Gertrude and Fortinbras are royalty. Royalty defines people of royal (of or relating to a monarch or their family) rank, plus their families treated as a group.
Where Gertrude was the Queen of Denmark and Hamlet’s mother, who was recently married to Claudius, Fortinbras was either the young Prince of Norway, or the father (also named Fortinbras).
Laertes and Ophelia were siblings and were children of Polonius who was The Lord Chamberlain of Claudius’s court, and was also known to be a pompous and conniving old man.
