Answer: D) the memory is fresh in our minds.
Step-by-step explanation: In the given excerpt from Act I of "Hamlet" by William Shakespeare, we can see the King talking about the death of Hamlet, he says that he still thinks of it ("Thought yet of Hamlet our dear brother’s death"). With the phrase "The memory be green" he expresses the idea that the memory of Hamlet and his death is fresh in their minds (something green gives the idea of being fresh), so the correct answer is option D.
