Answer:
A.) Appearance and reality.
D.) Parent-child relationships.
Explanation:
The tragedy play of "Hamlet" by William Shakespeare is about the story of Hamlet who avenged his father's murder at the hands of his uncle Claudius. Claudius had also in turn married his former sister-in-law, and wife of the King Hamlet, Gertrude.
Right from the start of the play, we see the character of Claudius talking of his grief in losing his brother, but at the same time, keeping his responsibility of saving the kingdom. His immediate marriage to Hamlet's mother also shows his insensitivity to the issue of his brother's death. His appearance of showing as if he really cared about the kingdom or even the death of his brother is in stark contrast to his reaction, his way of dealing things. His reality is that he wants the kingdom for himself and cared less about the others, especially Hamlet. Acting like a concerned father, he implores Hamlet to stop mourning his father. He also acted as the father figure to him, telling him what to do and how to do, advising him on his life plans. Thus, we see Claudius involved in the theme of appearance and reality and that of a father-son relationship.
