Answer: B death.
In Act V, scene i, Hamlet and Horatio walk into the graveyard, where they see the gravediggers digging a grave for Ophelia. Hamlet talks to them, and one of the gravediggers shows him a skull. He says that the skull belonged to Yorick, a court jester. Hamlet remembers Yorick fondly, and is very upset to find his skull and remember his death. Hamlet then reflects on the fate of all men, who die and end up turning to dust.
