Final answer:

Step-by-step explanation:
In Iliad Book 15, Athena disarmed Ares because Ares was interfering with Zeus's plans. Despite being the god of war, Ares's actions on the battlefield were in contradiction with the grand scheme set forth by Zeus, the king of the gods. Athena, the goddess of wisdom and warfare, often supported heroes and endeavors that aligned with Zeus's will.
Given her responsibility to uphold Zeus's plans, it was in her interest to disarm Ares and maintain the balance of power and fate as determined by the ruler of Mount Olympus. This move showcases Athena's strategic role in the cosmic order of deities, where she adheres to and enforces the hierarchy and decisions made by Zeus.
Hence, Athena disarmed Ares in Iliad Book 15 because he was interfering with Zeus's plans, reflecting Athena's role in maintaining the cosmic order and adhering to Zeus's will.
