Final answer:
The answer to the fill-in-the-blank question is 'incestuous.' Antigone in Sophocles's 'Antigone' talks about the incestuous guilt of her father Oedipus affecting her family.
Step-by-step explanation:
The correct answer to the question is A) Incestuous. Antigone is referring to the shameful act that gave birth to her and her siblings: the marriage between her mother, Jocasta, and her brother Oedipus. This incestuous union is the source of the curse that she believes affects her entire family.
The passage from Sophocles's Antigone highlights Antigone's view of the family curse stemming from her father Oedipus's unwittingly incestuous actions. Antigone sees herself as carrying the burden of this hereditary stain, which casts a shadow over her and her family's honor, leading to her tragic choices.
