Which of the following statements describes O'Hare's pet policy?

The statement that describes O'Hare's pet policy is correct because O'Hare Airport has specifically designated pet relief areas to accommodate travelers with pets. These areas are set up to ensure that pets can relieve themselves in a designated and convenient space, which helps maintain the cleanliness and comfort of the terminal environment.

Travelers appreciate this policy as it provides a necessary provision for pet care during layovers or before flights. It also indicates that the airport has considered the needs of pet owners, facilitating a smoother travel experience. Other statements do not reflect the policy accurately, as pets are allowed and must be cared for in a structured way rather than being caged at all times or barred from the terminals entirely. The presence of relief areas also counteracts the idea that pets can roam freely, highlighting the airport's intention to maintain order and cleanliness.
