The correct response is: **Large distances are easier to express in AU than in km.**
Astronomical units provide a more convenient scale for the vast distances in space, especially when dealing with distances between celestial bodies within our solar system. Using kilometers for such large distances would result in very large numbers, making them less intuitive and harder to work with.
