How do the prisoners typically respond during an air raid at Buna?

During an air raid at Buna, prisoners typically respond with fear and anxiety, making "Frightened" the correct answer. This reaction stems from the intense and traumatic experiences the prisoners have already endured, which create a heightened sense of vulnerability and dread in their circumstances.

The sound of bombs and the chaos associated with an air raid trigger instinctive fear; they are acutely aware that their lives are constantly at risk. The oppressive environment of a concentration camp further exacerbates this fear, as the prisoners realize that they are seen as expendable by those in power.

Other responses like indifference, joyfulness, or anger do not accurately reflect the psychological state of the prisoners in such a harrowing situation. Indifference would suggest a level of desensitization that is not typically applicable here, given the constant threat to life. Joyfulness seems wholly misplaced in the context of an air raid; such a scenario would hardly evoke happiness given the impending danger. Anger might arise occasionally, but in the face of immediate threat, fear usually dominates human emotions, particularly in such dire conditions. Thus, the collective response is rooted in fear and the instinct for survival.
