Final answer:
Haemon is promised in marriage to Antigone. He argues for her release but is rejected. Sophocles explores the theme of a democratic king through the tree bending analogy.
Step-by-step explanation:
The person who is promised in marriage to Antigone is Haemon, Creon's son. Haemon argues calmly for Antigone's release but is met with angry rejection from Creon. In the play Antigone, Sophocles explores the idea of what it means to be a democratic king through the analogy of the bending tree.
