Final answer:
In Shakespeare's Hamlet, by rights of succession and medieval standards of revenge, Hamlet would have a right to avenge his father's death and become king, but he has no right to indiscriminate killing or claims to the Norwegian throne.
Step-by-step explanation:
In William Shakespeare's play, Hamlet, the character Hamlet seeks to avenge his father's death, which brings into question what rights he is justified in his actions against Claudius. Answer A is correct, as by the rights of succession, Hamlet should have become king following his father's death. Answer C is also correct, as, by the rights of medieval revenge traditions, Hamlet is expected to avenge his father's murder. However, answers B and D are incorrect because Hamlet does not have the right to kill anyone he pleases, and he has no claim to the throne of Norway.
