How does the guard describe Antigone's reaction upon seeing Polynices's body?

The guard describes Antigone's reaction upon seeing Polynices's body as one that invokes a strong emotional response. This indicates that her grief is overwhelming, reflecting the deep love she holds for her brother and highlighting the tragedy of her situation. Antigone's scream symbolizes both her sorrow for Polynices and her outrage at the injustice of his unburied body, which defies the divine laws she believes in. This moment serves to emphasize her passionate and fearless nature, as well as her commitment to familial duty, which is central to the themes of the play.

The other potential reactions like smiling calmly, fainting, or crying softly might suggest a different kind of emotional response but do not capture the intensity or immediacy of her grief and resolve at that pivotal moment.
