Final answer:
The correct theme of 'A Good Man is Hard to Find' by Flannery O'Connor is redemption (a), as the story explores moral and philosophical questions about sin and forgiveness.
Step-by-step explanation:
The theme of redemption is notably present in Flannery O'Connor's story A Good Man is Hard to Find. This is particularly evident through the interaction between the grandmother and the Misfit, where themes of sin, grace, and ultimate redemption play out. The grandmother, who is flawed and self-centered, experiences moments of grace that suggest potential for redemption. On the other hand, the Misfit, a convicted killer, engages in a philosophical discussion about Jesus and forgiveness, which reflects O'Connor's exploration of redemption through violence and suffering, in line with her Orthodox Catholicism.
Therefore, the correct answer to the question 'Which of the following is a theme of the text "A Good Man is Hard to Find"?' would be a. Redemption. Other themes like betrayal, isolation, and wealth are not as central to this narrative as redemption is. While O'Connor's work frequently contains elements of dark humor and Southern gothic settings, these are not themes but rather characteristics of her writing style.
