Explanation:
In cosmology, the distance between the objects in the universe is measured by using units such as light year, light-minute, and astronomical unit.
Here, 1 Light minute ≅ 1.8x 10¹⁰ m
1 Astronomical Unit (au) ≅ 1.49 x 10¹¹ m
1 Light year (ly) ≅ 9.46 x 10¹⁵ m
Now, arranging the units in ascending order: light-minute, Astronomical Unit, light-year.
