i might be wrong but i think its C. characterization
The answer is all of these.
The Duke is the speaker of the poem where he is entertaining an emissary who has come to negotiate the Duke's marriage. As he shows the visitor through his palace, they came across the portrait of the late Duchess. The Duke then began to reminisce about the portrait sessions and then about the Duchess herself. As his monologue continues, the reader realizes that it was the Duke who caused the untimely demise of the previous Duchess.
Old age homes, or retirement homes are advisable for many different reasons. First of all, many of the elderly's children are not able to provide the needed care on a 24/7 basis. In the present day society, both the mother and the father have to work to be able to provide for their own children. By placing their elderly loved on into a retirement home, they are able to continue working, while entrusting their loved one with professional nurses and caretakers. These workers are able to keep a constant eye on the elderly, provide them with balanced meals, give them their daily medications, and provide physical therapy should it be needed.
There are three murderers in the scene. The action occurs at dusk (The First Murderer: "The west yet glimmers with some streaks of day.") The scene happens near the palace, in a park. Banquo and Fleance bring a torch to the scene. The First Murderer manages to put out the light, while all three of them attack and kill Banquo. The scene lasts a couple of minutes only, and the action unfolds very quickly. The dialogue is quick, with short, interrupted lines, which is logical considering the fact that this is a murder scene. At first, while they are waiting for Banquo and Fleance to show up, their language is wordier. But then, right before and after the murder, it is swift and abbreviated, telling us that the murderers are members of a lower social class (The Second Murderer: "Then ’tis he: the rest / That are within the note of expectation / Already are i' th' court.") Banquo's last words are that he is betrayed; also, the warning to Fleance to run away to safety. Banquo realizes in an instant that this is a political murder, and that his son is the next potential victim. So, he wants to protect him. We don't see from the text how Fleance escapes.
That’s fair, hope it works out
