Explanation:
Light year is the unit of distance and not a unit of time.
Light year is used to measure astronomical distances.
It is defined as the distance which light travels in one year.
The distance which light travels in one year is around 9.46 trillion kilometers
Thus 1 light year = km.
Thus the given statement that A light-year is the distance that light travels in one year is true.
