What must Gulliver do before leaving the city according to the Agreement for his freedom?

Before leaving the city, Gulliver must obtain permission, as outlined in the Agreement for his freedom. This stipulation underscores the control and authority the king and the state have over Gulliver during his stay in Lilliput. Despite being a giant among the tiny inhabitants, he must still adhere to their rules and seek their approval to depart. This reflects the broader themes of power dynamics and the importance of consent within societal structures present in the narrative of "Gulliver's Travels."

The other options do not accurately represent the conditions of his departure. While Gulliver interacts with the king and navigates his relationships with the Lilliputians, the formal requirement of obtaining permission from the authorities remains paramount, illustrating both Gulliver's vulnerable position and the rituals of governance that dictate his actions.
