I believe the best answer is D. The discrepancy between what is expected and what really happens as with dramatic irony, this could be quoted as a definition.

It’s no use waiting any longer; the time to act is now.

Answer: metaphor
Explanation:
Laertes uses a metaphor, which is a figure of speech that depicts an object or an action to helps explain an idea or make a comparison.
Laertes tells Claudius that héll obey his decision and that he wants to be the "organ" of Hamlet´s death, however, Claudius decides to do it. Laertes claiming that he wants to the instrument of death for Hamlet is a metaphor because he uses the idea of an organ, which could be a biological human organ that helps the body carry out certain actions or a musical instrument that caries out a melody, to represent himself as an element that can do something else than killing to state that he wants to be the killer.
A simile also compares two different things, but it does so by using the words like or as, so is not the correct option for this example.
Dramatic irony refers to when the audience of a play knows something that the characters do not know, and an aside has a character speaking to the audience, so neither is correct for this example.
