ALL of these.
Explanation
The three options - lightyears (ly), kilometres(km), and metres(m) - are all units of measure for distance. However, the selection of which one to use depends on the scale of the distance that is being measured.A lightyear, abbreviated ly, is a measure of distance used in astronomy and represents the distance that light travels within one year. This is typically leveraged for large distances such as those between galaxies or within a galaxy.On the other hand, kilometers (1 km = 1000 meters) and meters are commonplace units used to measure shorter distances on Earth. A kilometer is often used for dimensions like driving distances between places in daily life, while a meter which is the base unit for length in the International System of Units (SI), can be employed for even smaller distances, for example the length of a room or an object.To answer the question appropriate, the answer is "ALL of these" as each unit serves a specific purpose based on the actual distance needed to be measured and all three can be used for the measurement of distance.
