What motivates Creon to sentence Antigone as he does? A. his desire to protect his son B. his drive to maintain peace among his citizens C. his annoyance with women's behavior D. his cowardice about condemning her to death

B or C.  Both have themes in the story; the peace was violated when the brothers fought and Creon wants to be in charge of a peaceful city.  But he also is annoyed that the women have defied, especially Antigone.  The rights and social position of women is one of the themes that pervade this story.
