Final answer:

Step-by-step explanation:
Under the laws of armed conflict, a prisoner of war (POW) is allowed to engage in certain tasks. The correct answer to the student's question is (d) Engage in labor for the detaining power. POWs may be asked to perform work that is not military-related, dangerous, or degrading, and that is within their physical and mental capabilities, according to the Geneva Conventions. They should also be paid for this labor, and it should not be excessive.
Tasks like acting as an informant, engaging in combat operations, or sabotaging enemy facilities are expressly prohibited, as they could be seen as directly participating in hostilities or aiding the enemy, both of which are against the treatment standards of POWs as outlined in international law.
