Explanation:
Definition of a Light Year:
A light year is the distance that light travels in one year. Light travels at a speed of approximately 300,000 kilometers per second.
Calculation:
To calculate the distance covered by light in one year, we need to multiply the speed of light by the number of seconds in a year.
Speed of light = 300,000 km/s
Number of seconds in a year = 365 days * 24 hours * 60 minutes * 60 seconds = 31,536,000 seconds
Distance covered in one year = 300,000 km/s * 31,536,000 s = 9.5 x 10^12 km
Therefore, the correct answer is option C, which is 9.5 x 10^12 km.
