Correct option is C

A light year is a unit of measurement used to express astronomical distances. It is the distance that light travels in a vacuum in one year, approximately 9.46 trillion kilometers (5.88 trillion miles).
Important Key Points:
1. Light travels at a speed of about 299,792 kilometers per second (186,282 miles per second).
2. The concept of a light year helps astronomers measure vast distances between celestial objects.
3. It is used to describe distances within and beyond our galaxy.
4. Light years allow for an understanding of the scale of the universe.
Information Booster:
 Speed of Rocket measured in a year: Not a standard unit of measurement.
 Distance travelled by sound in a vacuum during one year: Sound cannot travel in a vacuum.
 Speed of Aeroplane: Typically measured in kilometers per hour or miles per hour.
