Which of the following is a legality concerning the treatment of POWs?

The option that states the allowance of the practice of religious faith is correct because it aligns with international humanitarian law, specifically the Geneva Conventions, which protect the rights of prisoners of war (POWs). These laws emphasize that POWs should be treated humanely and afforded certain fundamental rights, including the freedom to practice their religion. This provision acknowledges the importance of spiritual support and cultural rights, which contribute to the mental and emotional well-being of POWs during captivity.

In contrast, the other choices present actions that are prohibited under international law regarding the treatment of POWs. Denying medical treatment to wounded prisoners directly violates the obligation to care for injured individuals. Similarly, transferring POWs to hostile entities undermines their safety and protection, potentially exposing them to further harm. Withholding food and water constitutes cruel and inhumane treatment, which is expressly forbidden under the laws governing warfare. Thus, the option concerning the practice of religious faith stands out as a legally acceptable and humane treatment of POWs.
