The correct response is:
Large distances are easier to express in AU than in km.
Astronomical units (AU) are specifically designed to help simplify the representation of large distances in space, particularly between celestial bodies within our solar system. Using kilometers for such vast distances would result in very large numbers that are cumbersome to work with, while AU provides a more convenient scale.
