The tragedy of Antigone reaches its peak when (C.) Haimon and Antigone die.

The peak of a story is the highest point of interest. This moment is characterized by a great intensity and tension. Antigone, which was written by Sophocles, reaches its peak when the protagonist, Antigone, decides to hang herself after she is condemned to death by Creon for disobeying him and burying her brother. Moreover, when Haimon finds Antigone dead, he stabs himself. It is a moment full of tension, which has been caused by Creon's decision of not prioritizing his family over the state, and it shocks the reader, who does not expect the main character to die.
